His name is Rafael van der Va
art

. Anyways, this signature is quite good, I like it. The render effects are nice, they fit perfectly into the style and the double render thing looks nice, I just think the two renders could've been blended in better with each other. The text could be better, not so sure on it. Background is nice, I think it fits well and the stadium gives it the necessary depth. Try to make a border that fits better, this one isn't going so well with the rest IMO. Keep it up, mate
