I guess if I want people to critique my sigs, I have to critique theirs first //; I'll try to help you as best as I can ^^

1st: The red and orange shades are way too concentrated. Don't saturate it so much. The black thing didn't mesh well either. The colors are so one-sided to the point that it's boring. Your rendering here is nice though.
2nd: I like the font, but the rendering here is too pixely. It also looks way too simply done, it looks like you just slapped him on a texture, he wasn't even blended well.
3rd; same comments as the first, and the stock is poor quality.
4th; the background is ok, but it's unbalanced. Needs more CD4's/brushes to the left. The purple colours were meshed well, but I'm afraid they don't match the orange colours of the stock. The stock also wasn't blended well.

There are a few dings here and there, but that's expected if you are a beginner. I'm a beginner too, and I hope you can help me improve as well.
