I’d go with gilgamesh on this one, maybe a little hint of shadowin the temple area might help a little do define the heads shape and depth. I don’t know. As well There could be just a hint of blue within the material for the BG to help increase the contrast. Lightings looking better but still needs tweaking, and the drop shadow doesn’t seem quite right. Last comment for now is that the white tone of the forehead is too bright, It really pings, I check the image on my TV monitor and it really is intense. I would bring it down a ittle in brightness or even better hue as well.
VEry nice work, leaving me a lot of work to do for my first run.
