Music : nothing fancy, rather boring composition, does not provoke, does not induce any chill
Mixing : tends to be on the Lo-Fi side, optimize it more, give it more depth and breathing, it tends to be way too one-dimensional
Voice : to be changed. I think only French people sing that way, and I am sorry to say, it brings the whole thing down. Well, to be fair, the voice on "Le mur s'effondre" reminds a little of Trent Raznor (together with the drum beat and the overall feel of the song),. You must certainly be a fan on Nine inch Nails ;) But otherwise, you sorta belong to the same group Miro and other French singers belong to: flat voices sounding like teenagers experimenting alternative music for the 1st time. But it could be the result of the mixing ...
Anyway, to my mind, you have A LOT of work ahead if you want to exploit your ideas. But don't give up, "c'est en forgeant qu'on devient forgeron" as you French say :D
