I still have a (half) roof to do, but i'm on the good way !
But here is what i've done today:
Texturing the adjacent building:
Cutting windows borders:
Carving the paving stones on the terrace:
After that i press randomly a little rock to texture the depron on surface.
And the result of the work of the day:
It begins to look like what i had in mind at the beginning of the project
Sadly the progress is not as fast as i would, so i'm pretty sure it'll be not painted for the 24th august. Probably finished to built, but not painted :/
