Man I LOVE the aesthetic look of your tilesets. They're reasonably priced too. My only complaint for now is the lack of of any sci-fi elements to the overworld tileset. Fantasy is fine, but sci-fi and science fantasy especially are what I'm shooting for. Well, a guy can hope. I have no talent for that kinda art myself. Well, not anytime even remotely soon anyway.
Keep up the great work though!
