Okay, I am going to put this out there for those who don't know me: I do not do requests. Please do not ask me to sprite a tileset for your fangame/hack/whatever. If I wanted to sprite for your project, I would ask, but please do not come to me. I really don't like being asked (let alone pestered). So please, do me a favor and do not ask.
Also, about permission for my sprites: anyone can use the tilesets I allow people to use, with proper credit, of course. Please do not ask me to use them, as you do not need to and it kind of annoys me.
Now, I tried putting this as nicely as possible without flipping out. Please do not make me do so.
Anyway, Yuoaman, I answered your question in your userprofile.
