Ok, that is some of the worst shading I have ever seen, even if you were using paint. In my siggy, I used paint for my first one, and I like it. Try looking for some tutorials on shading, you dont just change colours all of a sudden, you have to blend it. And you can use colours other then the default ones. You go to colours, then edit colours, and the you can change the brightness or shading of the colour you have chose, which helps your shading. Also, look for tutorials on the anatomy, because that guy doesn't look good. I stick by my 1/10. BTW: This looks like you rushed it. In the future, take your time with it. You cant rush it.
