Skull King

This week, me and my siblings were 'banned' from the computer. I decided to sketch out a skull of my dragons from various angles and I liked the result of my 'non-referrenced' practice. Therefore I sketched a larger version and this was the result. I really like how it came out so I took it a step further and shaded it.

All that was used was two pencils - a normal and an extra black.
Time around three to four hours.
Critique and comments are always appreciated and taken to heart.
