First thanks a lot to Cedricgo and Rakskuder for their ultra positive comments!
These two pieces will be my submission for the contest. I turned the character a little, because I feel it's a bit more dynamic, and I wanted to see his left eye as well. The top hair is thinned out quite a lot and I tweaked the lighting to get rid of the over bright areas, as well as trying to let the scene look a bit sunnier.
The final render comes straight out of Cinema4D/Redshift ... no retouching or grading done.
