This tag is nice, but the background could be a little smoother, and you got a nice color scheme right there. the only thing that really bothers me is that yellow thing on his left eye. nice tag.
Hey Chaser =D Hot tag lovin the background. The effects as you said are simple and it looks great. But those things in the top right corner throw off the flow near your focal point and are kinda distracting. Also the lighting in the background doesn't match with the focal, i don't know if that the stock but it doesn't look balanced. Maybe some yellow soft brushes over the bottom of the focal to balance things out? HOTNESS!!
Only thing I want to see have work on is the text. Far too simple, even though it is a vector masked layer. Otherwise I like it quite a lot. Especially the colors. Very pleasing to the ye.
