Nice work
Wow I have to say this was some nice work, I like the darkness of this, and his staff that star at top of the staff could have a sparkle and shine on it though, and you could use some backround work on this one, but honestly you have some nice shades and nice structure on the character.
~~THINGS TO IMPROVE ON~~
Some backround work maybe some scene of darkness, and have that star shine or glow.
