Zagachan
First, but both of them are terrible.
It's not showing enough of the body to tell me if your anatomy should be improved massivly, but from what I can see it looks quite good.
Practice your shadows and your composition. It won't hurt you at all to practice folds and colouring either. Look up tutorials on the net, they help.
Good luck.
Dear Zagachan the coloring in this picture shouldn't be taken seriously. I was testing some of my copic markers. As well as the picture its was done out of fun not out of any seriousness. The original picture is done a lot differently and doesn't have much relation to this picture. (that one is the one you should critic not this one.) Also this done by hand then i scanned it. I tried to get the original colors back but as you can tell I couldn't. A Lot of the shading is gone. There is no way I can fix it.
This also is my cartoonish style, folds and everything else is warped and again is not to be taken seriously. Your critic would be greatly appreciated on some of my other pictures but this one is one that didn't really need it.
thank you for understanding!
