Defeat and Victor for Castile
Following Granada's victory in their war for independence against the Kingdom of Castile, Aragon was able to score a major victory against Castile. They forced the Castile to give up Leon and recognize that the King of Leon was independent from Castile. They did so but did so begrudgingly.
The fortunes of Trastámara looked bright following this victory. While they did claim Leon as they saw themselves as the rightful kings of Castile and Leon, they were focused on claiming Castile's throne first. Peace between Aragon and Castile brought another player into the affairs of the Christian kingdoms of Al-Andalus: France.
The Kingdom of France entered the picture with Aragon's victory. They had chosen to side with the Kingdom of Castile. With Aragon's departure they had brought their forces across the Pyrenees into Al-Andalus to fight Trastámara and their supporters. Both Castile and Trastámara had exhausted themselves by fighting so far with the arrival of the French Knights the war quickly turned against Trastámara and their supporters.
A look at Al-Andalus following the Castilian Civil War

The peace that had been achieved on Safar the 28th 768 AH following the end of the Castilian civil war and the War of the two peters was a tumultuous one. All the kingdoms sought to make moves against one another in the power-struggles for Al-Andalus. As the outcome of this conflict shaped how the kingdoms moved against one another; it is best to do a brief summary of the various kingdoms and where they stood in 768 AH.
Leon
The Kingdom of Leon was created out of the Kingdom of Castile. The new King of Leon, Carlos the 1st was of the Vilafermosa dynasty. He was a cunning and scheming man who switched from supporting Trastámara to taking the throne of Leon with an arrangement from Aragon. He did though offer sanctuary to the supporters of Trastámara who didn't want to be killed for supporting the losing claimant.
He sought to expand the power of Leon at the cost of Castile. In particular he wished to extend northwards to the Cantabrian Sea as well as into Galicia. This naturally brought him into conflict with Pedro of Castile. His main issue is that he had to begin training brand new levees and winning the trust of the local nobility in order to pursue his expansionary agenda.
Castile
With this peace Pedro the Cruel was able to hold onto his throne. He did live up to his epithet and harshly punished the supporters of Henry Trastámara. However there were two issues facing him following the peace: instability and the Loss of Leon.
Despite holding onto his throne, there were still many threats to Pedro's reign. The wars that he waged were brutal and had exhausted his own treasury. Though he crushed the main nobles conspiring against him, there were still many who resented his rule. Banditry had grown up with the start of all this fighting and following the peace, there was little done to stop it. The trade routes were deserted of particular note was the popular pilgrimage road of Way of St. James.
The General instability of Castile is of note because it was something that all the other rulers in Al-Andalus saw be they Christian or Muslim. The instability coupled with the prestige loss from losing Leon meant that they levees and men that Castile called up to fight were not going to have the best moral.
The Loss of Leon was a major loss for Castile and for Pedro Personally. Pedro called himself king of Castile and Leon, though he had to acknowledge that Carlos was the king of Leon he did not like it. This meant more manpower and trade was now taken away from him. The fact that he sheltered the Trastámarans was just another insult to Pedro.
However the biggest issue was that Castile and Leon were now at each other's throat instead of being part of the same kingdom. This was something that the Nasrid rulers saw right away and worked to make sure that they were not united again.
Aragon
Of the Kingdoms involved in the wars, Aragon came out of the conflict rather well all things considered. The regency council for King Enric de Barchinona was able to keep their power. Pedro saw himself as the King of Aragon in addition to his other titles and the King of Aragon forced him to change his mind on that notion. The regency for the young boy-king was able to survive.
It should be noted that during this time, that while Aragon got peace in Al-Andalus they had to fight in Sicily. The Kingdom of Naples was seeking to push into Sicily at Aragon's expense. Aragon's Mediterranean possessions and the desire of the King of Naples to claim them is a recurring theme throughout this era of history.
Portugal
Portugal came out of the conflict somewhat better off. Despite being part of the same dynasty as Pedro the Cruel, Alfonso the 4th of Portugal fought against him. His defense of his kingdom helped earn him the moniker, the Brave.
As the Peace ended they were able to work on restoring the relationships with Castile. This helped make it so that they could have an Alliance again. Should Granada or Leon expand against either Kingdom. Though it was the alliance with England that would make that a tad more difficult to deal with.
Granada
Granada came out arguably the best. They went from a tributary state to one of the major actors in the politics of Al-Andalus. The conquest of Qadis, Walbah, Ishbiliyya, and Antequera began the reconquest of Al-Andalus by Granada
The cities of Qadis and Ishbiliyya were good sized trading ports even in this era. Helping to link the Trade Routes of the Maghreb with the Al-Andalus. Though, their real rise to prominence in the area of trade would happen in the future.
Following this peace, Muhammad the 5th made plans to set out for the Hajj. Though before he set out for the Hajj he made sure to begin the long process of restoring control to the newly conquered provinces. This was also accompanied by declaring himself Sultan of Granada.
It should be noted that all the Christian Powers in Al-Andalus distrusted Granada; though Carlos of Leon distrusted Granada the least. This distrust and Carlos of Leon's deceptive nature would play a major role in the shifting alliances that were to become a key factor of the conflicts in Al-Andalus during this era.
