Nice work Boco!
You're improving so much it's insane! Your anatomy's lookin' good as well. c:
You've got such a neat, smooth airbrushed style. The line-work is very neat and consistent, too.
Overall, I think the only thing that bugs me a bit is the composition being a tad imbalanced. Seems like there's a lot of open/un-used space on the ride side that could be cropped and moved around a bit, but the image still looks good either way.
Keep it up, and happy belated halloween!
