pink c4d....Killzone render...... poor match really
i mean cmon man thats a war guy, pink will just look awful on him
and thats not even blended properly.
here is what you do, if you think that the c4d u choose was fit for your sig, just change its color by selecting the c4d layer and pressing Ctrl+U
this will open a hue/saturation filter that will only affect the particular layer that u selected.
secondly, try blending the c4d with the render. the render should be more visible rather then the c4d's. C4d's are to support and not to become a focal themselves.
in your sig that is what happening.
and what is that face doing there below the render? If its a part of the stock then either make it visible or smudge it off or cover it with effects.
i think u tried to cover it by placing c4d's, and that was bad idea. if you have not put the c4d on lighten it would have been much better,
seeing your signature nova. you can do much better then this,
want to see much better from u next time
