Wow! I thought you were just going to be some stupid kid with mediocre drawing skills that wanted easy money, but these are amazing! I'll give you 10 BTC to make a logo for my minecraft server. Try and be creative with it (From the looks of it, you won't have any problem with that,) and make it evident that it has to do with minecraft. Maybe one of your stick figures leaning against a generic dirt block like this one?

It wouldn't have to be isometric like that, or even include that at all. Just make something in your style. Just an idea, I'm not the creative one here. Let me know if you would like more BTC than that.
