Not familiar but great picture!
I am not familiar with Street Fighter Alpha. Geez, you would think a guy on this website would know everything there is to know about every popular video game. I can still appreciate the wonderful work done to show this character. It really helps that you show the sprite version of him in the background. It pretty much puts every sprite work out there to shame. It's been awhile since you've submitted a plain old cartoon or at least something with this artwork.
I like how there's so much detail put into every and every little crevice this character has. The best part is the shading because his body is covered in it. The outlines are not black, but instead they exist through the color of the character. It makes me appreciate all the hard work and effort put into making stuff like this. You can't see a single sprite cube in this!
