Undead Dragon

Drawing this was pain, it took almost 5 hours from me, because I'm pretty slow to draw. I don't even know how realistic the flesh looks but at least I tried. I'm personally happy with those scales since I'm not good drawing them. Pencils I used while drawing this were 9B, 6B, 4B and 2B. To add a bit color, the flesh is red and internal horn, eyes underside of the neck plates are green and it has a little  bit bloody teeth.
