I like this art, because the drawing ist simple, but stating, too. The background is very good, It shows that the hero ( apparently Superman ) is moving. The background is underlining the moving! I love it!
That's funny, I was trying to do something similar the other day [link] You managed to evoke speed a lot better though. How did you get the radial blur to focus on the right like that? Whenever I use it it always stays in the centre of the picture, it's really annoying you can't move it
