>Request an sketch

>Post a sketch

Shouldn't it be "a sketch" on the first sentence too? To be honest, it hurts when I read it, but that might be just my OCD.

Also, is there anything preventing people from getting the sketch without paying its author? Perhaps you could give people only a thumbnail of the image and only if they pay the author, can they see the full original size image.

On another note, I really like how you explain the purpose of the website on the top header without many words.
