I been meaning to do this for some time now, and THANK you Sonic Generations XD for the spin Bio image of Knuckles I was able to do this finally.
I had to turn Knuckles to 8 angles just to get this, his hands and shocks was the hardish to do.
I just coped everything I could as best as I can from the image on the game.
and here it is Sonic in turning angles to help people draw him.
also I plan to do this for 3 more of the chars, just now Runnic and a base to do hehe
then with them I gonna make some base turn angle Sonic poses for everyone to use ^^
