Shadow on the run

I was so fast with this one, amazing...only a few hours and then it was done...just playing around with squares (and then I had to add my own version of the background of Sonic Generations haha).
Anyway here's my fave: Shadow running at the speed of sound. It came out really modern, that's why I like it. He also looks quite happy with all these colours...why always so dark for Shadow?
