Nice and epic.
This drawing looks epic, it looks really realistic and very...evil and dark, which I like. (That sort of feeling). I noticed a few "unfinished" areas and I'll point them out.
1. Shadows. (minus 1 point)
Yes, the dark shadows aren't as perfect as possible, but I'll have to admit that you did a great job on this. Maybe you could have shadow some more and make it look even better? It's your choice.
2. Left side of the pic. (Neutral)
I see a white zone on the left of this drawing, which is something I dislike. But since your scanner isn't perfect, I will not count this as a con.
3. No color. (Neutral)
I would really like it if it had color in it. This is, indeed, very hard, but maybe you could continue to work on it and make it look SUPER in color. It depends on your choice! Since it's really hard to add colors (or you don't want to) I'll not count this as a con, either.
So overall, 9/10 (aw, I can't vote) and I'm hoping for a colored version. :P Or a new drawing. :) Then it would be great!
