This is so cool!
Looks great on a T-shirt too!
I can't get over how well you rendered those glazed, haunting eyes. Dolls are such a naturally creepy subject to draw - perfect topic for Halloween. The horns are really nicely rendered as well!
My one gripe is the detail on her neck--but that's just my personal opinion. To me, the fact that the blood seems to be flowing up towards her head bugs me a bit. Stitches or cracks may have been a little more effective to differentiate the similar bloody smears/makeup you used near her eyes. Not necessary though.
You really have a knack for eerie/dark subjects...! It suits your style! From what I can see, you're a very versatile artist, too! All very quality stuff.
Keep up the lovely work. c:
