I've never drawn any official Sonic characters (cough, besides Rouge, cough).
This one is pretty interesting! ^_^
The picture should explain a story:
Tikal wants to touch the chaos emerald in order to somehow preserve it. Yet, Chaos 0 wants the emerald in order to transform himself into a more powerful creature (soon-to-be Perfect Chaos, ref: Sonic Adventure).
Knuckles became sensed something that isn't right: something bad might happen that will soon lead to chaos.
He must find a way to stop this mess before endangering Mobius.
I've used two sheets of copy paper to create a more proportional drawing, since I'm trying my best to practice my method of gridding.
I've even used a white gel pen for some parts! (shweet, yea.......)
Edit: Woah! This is almost in the front page! *o*
.... I'd never expected that it would have so many views this time! XD
