The only thing I don't like in this screenshot is the roof tile, and that's hardly your fault. It's quite blocky and just... ugh. Oh and, here; colour edits for the wall cracks so they look like they're made out of the same material as the rest of the walls. ^.^
Thanks, guys! And yeah, I can't stand the roof tiles either. I understand why Kentona used the black backgrounds instead, but I don't want to rip his style off -too- much :)
