Im sorry im doing a lot of comment cuz i see a lot of problem
The doors are on the same tile
Im love symetry but its impossible to make it with your tilesheet, the window make 4 tile but the door for example make 3 tile its not a real problem but it trigger me xD
and i don't comprend how to do exterior :
i've made this and its not very good :p
again sorry i'm making a lot of comment but i think it can help you to draw best tile sheet (this one is beautiful but there is some problem)
