Yeah, I Haven't touched PS in a good 3 months. Here is my first signature in a pretty damn long while, its not to great, but i like it. (SOTW entry, lawlz)
I only personally don't like how the colors change through his face. Other than that, it's good. Better than my first-sig-in-a-while xD
You're whoring the purple orange gradient maps. They don't look as great as you think they do. Work on lighting, atmosphere, and depth.
I absolutely love your abstract style huntar, I wish I knew how you do most of it :3 The only thing I'd suggest CnC wise would be to work on Depth and lighting a bit.
