Complete Shot character illustration

[Helm]

Ok the style works throughout but I'm not too sure about the width of the outline changing from bit to bit. I think you should either work with the fat outline of the hair applied throughout, or de-emphasize the outlines a bit by using variable widths, but making them all a bit closer to the one used on the right (his) hand. The curving's good throughout. I think you gave him too much of an upper leg on the bent leg there and the fist coming out way has some curve issues (namely on the thumb and where the paw connects to it also)

I suggest a stylish two-shade to be used on this. Maybe a blue soft shadow, to be applied in proper anime glossy style.

Otherwise, this is good. The signs on the shoes are very very thin and detailed, which does not work for this image. You need to convey detail without actually putting in there, to pull off this kind of stylization. Think of how you'd see said signs, if you blurred your eyes and made out only generic shapes. Don't equate miniscule detail with thin outlines.
