Needs some more color, the bg style oesnt really match the render. Try to get the bg color to match the render, not the other way around. Text needs a little work. Read some tuts. 5/10
Not lovin the colors or brushing. The border needs to be over the render. To much empty space on the left. 5/10
Top, colors dont seem to match much. BG needs a little blue for my taste. Nice text. 8/10 Bottom, need to see the original. But i like it.
hmm well i can say that they are different that what i have seen before. but they are very cool gj on them 8/10 for both.
i think sonic doesn't really suit a grunge sig at all, maybe a vector or abstract. 5/10 the photomanip doesn't look like you've done much to it. 6/10 the third one is well blended and well made 7/10
