TMG!!!!!!!!!!!!! MAKE SUPER SONIC BUFF, AND MY LIFE IS YOURS!! (i really enjoy me some good buff super sonic, it's so cool)
For eggy... First off, he needs a bigger body, i get it's like your style, but i feel he doesn't look as y'know, egg with them long ass legs. I feel B's jacket look is a bit too complex, however, if you put B's scarf-cape, logo and the shines on the boots on A, it'd be a really solid design, or maybe mix both of the scarf-cape designs. Suprisingly, i think B's pallete works better if he were to be side by side with Sonic, i think it'd be a good contrast.
