Friendly battle

For contest.

just make a sketch of oficial Sonic Characters smiling, well, i wanted to do more, not just a smiling, i wanted to show they are happy, i don't know if i manage to do it, but i thoug to represent Sonic and Tails as brother playing to do a friendly fight, i use to think on them in that way, as brothers, actually, they are brothers, they grow up together fighting against uh... baldy mcnosehair....
there is also knucles, not sure why do i put him, but he is also smiling
