I wanted this one to feel somewhat flat, but I can see how it looks unfinished. The breaks in the outline are pretty intentional, especially on the wolf parts to make it seem a little more furry.
I like the design but i don't like that the drawing looks incomplete. I sugest you to pend more time completing the border lines and fixing some spots. You can also add more colors to generate some aliasing and/or practice the dithering.
Mmmm, for me is an sketch that needs to be polished. Howeva, GL.
