first off you see that middle line thing cut it off when you go to his face... or something.. or is it just pixel strech... i donno makes your whole sig look very odd. its an ok sig
needs work. seems over contrasted, render doesnt stand out enuff, needs a focal point. bit chaotic. could use better text.
those lines on his face kills it and ya over blended adjust levels on render also that light spot on right side is main focal point almost rendering the render invisible.
