Chibi Sonic the Hedgehog 3 - ECS collab

I asked to let me color her drawing of those chibi Sonic characters and she accepted. ^^ I can't resist the cuteness of how Knuckles look, so I just had to color it. o_o I've tried shading the picture but things didn't turn out too well so I left it flat. It looks better that way, anyway. =) I tried to draw a background like from Sonic the Hedgehog 3 game cover but I made it look to simple-like, but I like it anyway 'cause they fit well there. I drew the Chaos Emeralds in it 'cause this is like the part where Knuckles knocked Sonic down and dropped the Chaos Emeralds at the beginning part of the game. =)
