Then again, so would alot of peoples sigs be unicolored if thats your definition of it. *looks at your sig* Unicolor would be ONE COLOR- i believe i see white, black, flesh color, brown, tan, yah yah. Well whatever, thats your opinion. Anyway- i think this one is nice, you used your colors well! First off, I'm not saying his sig is bad, I'm just saying, that more color could be added, as there are plenty of colors in the render. You see different colors on his sig, because that is the contrast cause by the brushing/levels, or whichever contrasting method he used. I do believe he did use a color balance layer. On the other hand, I used many different layers of coloring, using soft grunge brushes, on layer style "color", it is many shades of the color you see. My point is, he should fully use the render's color, so the sig would not seem boring. Overall, the only fault other than the coloring I see is the render, and 3d renders dont match the bg well, although the brushes match the Army "genre" of renders. Err, well first off- you dont have the PSD file in your hand- therefore you dont quite know what shades of the color he used. I see your point but i think it looks fine- not great - but ok.
