How can I make the side door and side walls fit the perspective more correctly? Now It looks like the character is sitting on top of the wall for the side doors that are open.
UPDATE I recolored the wall tops, made the side walls thinner, added a 1 pixel layer of visible side on the inner wall face of the side walls. I think it is a big improvement. Still not sure about that open side door though...
UPDATE UPDATE I changed the side doors, partially based on suggestions. Still not perfect because the feet overlap the top of the wall but not much else can be done.
