First of all, a beautiful piece. the shading of it is astonishing. you have seem to put alot of thought in the shades of the hair. your technique of cross hatching this makes the work look like you own. however, i can see that this was somewhat rushed in some places. right now you probably need to focus on your patience and steady flow with the paper. as an artist myself, i still have the same problem. but overall, this piece is absolutely stunning and magnificent. please let me know if i have helped in any way and thank you for sharing your art with all of us here on deviantart.
