Pretty cool but I think you used filters and no brushes and i don't like fliters they are annoying but none the less good job um 6/10 (and its backlash or backslash Rafter I pmed u the link!)
1st...pretty good 8/10 2nd...not very good, sorry...4./10 work on your text and background, render.../everything...
Top, i like the whole thing but the s and the c in ur text. 9/10 Nice colors and texture, dont like the brush over half of his arm shooter thingy. nice text 9.5/10 I need to see the original to rate.
