So i tested a little your translation, for the most part it's okay, need to polish it a little but at it's current state, it's already good.
But i've found some errors, not really big errors but i will report them nonetheless. First one is when you're starting the game, when they talk about the unique skills of arcane mages, the "heal" and the "the" are close each other, touching even.
This one i don't know if it was here even with the MTL but when pressing shift, even when Mylene is not talking at all with anyone, it's hiding the text.
The rest is coming with two pictures.
("Tell" and "you touching each other)

(Has only done it the first time picking up the quest, after picking the other quest this error was not here anymore)
