Looks cool.
I like it.
I like how you chose to have him bald. Most elves are depicted having hair. I guess because hair is part of the over all package that helps make someone beautiful/handsome and artists prefer to have elves be a comely race.
The tattoo on the forehead is cool too. Heh heh, I do that a lot as well. I drew this one dwarf one time and I put a tattoo on his bald head. Perhaps some real world asthetics seeping into our fantasy art?
Maybe.
Your pose is nice. Seems to personify the role well. Since you mentioned his left hand; the only thing I can think of to maybe tweak it, is to re-do the thumb.
Are you left handed or right handed?
If you're right handed (you, the artist, not the Sorcerer/Noble) just pose your own left hand coming at you from the same angle and gesture (for reference) as you re-draw the hand. You might've have already done this. But don't be shy with trying again. Even doing it real slow and tediously. The time you spend will be worth it. The hand is a major feature of the composition and when you pull it off nicely it will be worth all the headaches you went thru to get it right.
Anyways, keep up the good work. Can't wait to see more from you.
