This was one of those drawings where I sketched it out and it looked great... But after I scanned it and began working I ended up hating it.
After two hours of frustration, I closed it and went to work on some other stuff. On a whim I reopened it last night, and wound up going a totally different route as planned. End result: I'm really happy with it! There truly were blood, sweat, and tears in this case.
