I don't really know what to crit, at first I wanted to tell you that maybe you should try connecting more of your lines to the rest of the "body". Discarded that idea. Then I thought that maybe you should use a larger variety of lines...discarded that idea too. I just don't know what to crit.
Everything else than the wolf man from imagination? Great!
You have the forms rather nice on, so I'd really like to see some rendering though. As in black and white, there's some good rendering on the coloured ones, but not too much on the B&W stuff. Also, even though it looks great, some cold colours might look good in the last one, the wolf guy?
