LQ? The face is overly sharpened. I think the image is the exact opposite of LQ its too much HQ. Fix the sharpening on his face and lessen the width of the signature. The head seems to be very very tiny with a long width like that. I like the C4Ds, however.
The second versions is better then the first, but it still looks oversharpened. You don't always have to sharpen for depth, there is a blur tool as well.
whoa, awesome. the color scheme is cool, tho i see the c4d on the left hand side that doesnt go very well with your "effects"
