|Start with an oval, because Knuckles' head is more oval-shaped than Sonic's.
||Give him a pair of suspicious eyes. A butterfly shape like Sonic again, but more squashed
out. Put a tall oval under the big one. Knux is all ovals while Sonic is all circles.
||Add his muzzle and dreadlocks. His muzzle is a vague triangle shape, because he has a longer muzzle
and more of a chin than Sonic. Rough out a couple lines for his legs and two circles on either side for his fists.
||Add his face detail and the outline of his shoes and socks. Give him a dissapproving look,
like the semi-villain he is.
||Add the last details and finish him out. Add his signiture white crescent, knuclaws and
latches on his shoes. And there's Knuckles, looking down his nose at you. :-)|
