Thanks for the feedback!
I'm not sure how far you read, so I don't what to say about the side characters. I write in third person, but I do try to stick to one character's point of view. I suppose that limits the development of other characters. I'll try to work on that. Sorry it didn't interest you, but I'm glad it's maybe an easy read? At least my MC is good. 
The translating without translating is for all the people who don't speak French, I guess. I didn't want to sacrifice that part of the character, but also didn't want people to miss what was said most of the time. Perhaps I don't need that and the reader can just not know.
