hi.
i'm not french. So i can tell you my opinion only about the screenshots.
First Screen : the title.
It's ok.
Second Screen : the room.
Many errors. Is it his house ?! Does he live only in one room with bed and table ?
A-and.. the bathroom...without a door and a washbasin ?!
You can add a door and many objects that you have in your bathroom.
The walls is so hight for this elements. It must be of only two square.
And replace the tv in a isometric graphic with a tv in a 2d graphic. You can't use isometric objects and 2d objects in the same map !!
p.s. and you can put the table near the fridge.
Third Screen : other title.
it's ok.
Fourth Screen : town
the two chara on the left have a different graphic... use the same style !
And you can put a house on a different line of the other houses.
The screen will be more dinamic. You can add also more tree.
Fifth Screen : inferno
The same error of the second screen. A isometric object in a 2d map.
And you can use a different faceset for the devil...
sixth screen : shaka
shaka have a very small faceset...
seventh screen : plane
it's ok. very good.
eighth screen : the face
ok... only the faceset down on the left O_O
nineth screen : cloud and flames
it's ok !
tenth screen :
very good world map ! Only the plane on the left should be changed.
eleventh screen : battle
the chara are different. some have very double contours, others very fine, others do not have. choose one style and adapt it to all.
twelveth screen : the car
a car... but a door in wood ?! A inn ?! And put the lamp one square up
thirteenth screen :
same montains are different. same woods are different. use only a type. And the same error... isometric object and blabla
the last screens are ok !
Good work
