Just as the title says.
This beauty wasn't all drawn by me. I mean, yeah it was, but I watched a how-to for this. An artist on YouTube made a "How to Draw Baymax". I'm subbed to him, and nearly every how-to he makes, I draw along with him.
His name is Mark Crilley for those of you interested. He's also the author of the Brody's Ghost graphic novel series, and the Miki Falls graphic novels. Plus, he has some How-to books on manga and a new Realism Challenge one that came out just a month or two ago.
You should really check him out, even if drawing isn't your thing!
