This looks amazing. The high contrast trick is really great for bringing foreground elements into focus (necromancer, crystals) and dimming out everything else - really loving how the skeletons are just silhouettes. The necromancer himself is vibrant and detailed, though as has already been pointed out the right arm is too long. I also wonder what would have happened with a bit more contrast - I notice the darkest shade of gray you use is still rather pale.

Arm's too long.

The painting and perspective is better than anything I could do. But I gotta say, the necromancer's arm is too long. He could touch his elbow to his hip without bending over. Do you know anyone who can do that?

Nice

Good work in my opinion , but i give 8 only because the skeletons look to much big in comparison to the necromance , and one of the hand of him are small , but is nicely done.
Anyway serously 15 hours of work?
Sorry for mine english xP
