It looks like they're in mid air. Where's the floor?
And it looks like you just drew a screenshot.
Not bad, but not good.

This sort of is like a 'blimp' view of a fight, almost anyway. I thought that was what is was at first, but the way their feet are positioned really don't allow that. So I am supposing you just drew the characters in a fight sequence over a BG that you drew first.

This looks pretty good though, even if it is on graph paper, but thats easy to ignore as long as you don't think about it. Quan Chi looks nice for the most part, his head looks a bit odd to me though. Muscle lines are fairly well placed, as this is more of a largescale drawing. I don't really like the way the skull looks though, the chin seem like its way too long. However, Raiden has been drawn very well, he looks basically perfect. Interesting drawing, but I would like to know if you meant for this to be a 'blimp' view, or did you just drew them over a background?

well, as stated it does look liek a screen shot, and it is flat, but other than that not bad, there is an odd break in quan chis arm that looks aquard, worth another look.

decent at best for a sketch

needs alot more shading and texture

when you make (if you make) a final verison

Well, I did actually draw Rayden and Quan Chi first and added the background later. But now that you guys mention it, it does seem really weird . Anyway, thanks for the comments and I'll try to give more attention to the things you said in the future.
