Super Sonic: What I'm Made Of

I drew this after finishing Sonic Heroes, which I find pretty cool, even though many people complain about the many glitches in it, not to mention the extremely shiny graphics. I feel that Heroes was all about friendship, which is why I made sure Knuckles and Tails were in the picture.
Even though this picture is called What I'm Made Of, the quote I used is actually from All Hail Shadow(Both songs by Crush 40), but I feel that it's out of place in a song about Shadow, who I regard as more of a puppet or a weapon rather than a hero, so I used it for this scene.
