^Ignore the pink line on the top, I'm really not sure how it got there, and am totally unwilling to remove it from this piece of crap. Yeah whatever. Edit: More ****
First one might be a bit too bright for this white forum. It's not bad though. The second and third don't appeal to me what so ever whic is odd since I usualy like your art. Honestly none of these wow me to much. I know you can do better, but I'll cut you some slack since you probably havent used PS in a while ;o Anyway, the last one is the best IMO, and it's still not super awsome. Too much negative space. Maybe have some effects down closer to the bottom left corner. They don't have to go all the way there just fill that side a bit cuz it looks too empty to me. And those wiered blurred black blobby finger print looking things to the left of him might look better if they were gone and replaced with some other effects. Also maybe you could through in some of that awsome text of yours if you manipulate it the right way.
Not your best work man. The Cin and RIS logo's are magnificent, but the first image looks a bit to bright and WAY too overdone with color and effects. The last one looks like you over did it with the "negative" effect. 7/10 overall.
