Whoa... Absolutely amazing... I really like the proportions. Especially since in the games and such, Sonic's body always looked too small for his big head, in my opinion. XD And Eggman looks really awesome as well, that mustache is epic.
KICK ASS- Oh gee, my leg broke, so I guess I need a stronger boot to kick some hardass "ass".
Joke beside, you did a wonderful job draw a man in the Egg side-to-side with our famous Hedgehog! I love how you threw in some "spit" effect on this picture (for easier to catch; look at Sonic's red shoe, right one) that made it look more reality, almost as if they just came out of the rain mess.
