I tested out exaggerating some of Kenny's proportions, and may keep a few things. I think I'll extend the inner black point of his ears to halfway, and the snout looks more fox-like when it's a full head long instead of the half-head long of today's Kenny. I like big tails, but I'll keep his a manageable length. His cheek tufts didn't need changing. His ears actually look smaller here because of the tufts.
His torso is twice as long here, and it's not noticeable. It may just be because the legs aren't showing, but still that's a good sign, because he'll continue to grow. I think I'll bump it up from 1.5 to 2 heads tall tonight. This torso here is 3 heads tall.
And the hair, yeah, he's a punk. I think it's still too short for him.
