Sonic doesn't stand a chance.
I love this design! It's great to see that you're advancing from busts to full-life characters. I don't really see anything wrong with this design, maybe too much dark shading on the face but other than that, flawless. Then again, I'm not by any means an expert on ZBrush, or Photoshop for that matter. I'm just giving you my personal opinion in hopes that you enjoy a bit of criticism. Keep up the great work and I look forward to seeing more from you in the future.
Glad to see you come off Busts and into full characters, keep it up.
Um yea if Mario actually looked like this i would be scared to play Mario games but this is a cool pic he is one of my favorite characters from back in the day
