Look, Love, Criticize.
Thank you for the maps. First off, Way to much Visigothic culture in Aquitaine. Limit it to a strip from Bordeaux to Toulouse and also Septimania (Mediterranean cost). There is evidence that there were Visigothic settlements in Catatonia so put a little Gothic culture there. Secondly, The centre of African-Romance culture was based in Carthage andthe surrounding regions. They remained a significant force there even until the 13th century, on your map it's all Berber. Finally Germanic Paganism all the way down the Rhone? It was one of the first areas of the Western Roman Empire to Christianize. The Archbishop of Lyon was called the Primate of the Gauls for crying out loud.
