Hey guys, i have a picture that one of my class mates drew and for the life of us we cant make it into a computer animated picture. All i want is to do is take the picture, and make it so it looks like it can go into a video game. I dont really want it 3d, but shadowing would be nice. Can anyone help?

Here is the picture:

You dont have to have the "Comet" letters at the top, but it would be a cool plus.

Thanks in advance DV.
