Frankly, I'd have to disapprove of Lanya in its current state. A nation stuck in the Adriatic, completely surrounded by A-H, and with no naval bases in the med whatsoever.
How did they even manage to colonise anything again? I'm suspect of its ability to even exert its influence in its own backyard, nevermind anywhere else. Remember, the Med was a hotbed of naval activity for centuries- so very high standards here, and I see little reason why this would be different in this mod either. Make sure you give it a few naval bases to exert influence, and I'm not sure where Lanya colonised exactly, but it most definitely needs a way out of the Med, whether it be direct control of Gibraltar or Suez, or a long history of friendship with whomever that holds it. A colonial empire is rather difficult to run if your only routes to your colonies can be cut off by your enemies at a whim.
Remember, the great colonial empires of OTL were able to carve out their colonies because they had free access to the Atlantic.
Oh, and you'd probably want to think about how the A-H, Lanya, Ottoman relations in the Balkans worked, to come up with a plausible reason just how Lanya managed to have enough resources to go out colonising in the first place instead of busying itself in trying to stay independent while being squished between the two.
