I like the EGA one, mostly cuz of his expression and how his eyes go red when he's frowning. The other one is so constant. They're both really kool, and I could see someone using the shaking version on a video game forum or sumpin. Dunno, left one is my pref. Awesome work, btw.
I prefer the shaky one, mainly because I like the color choices better. For some reason, I just get wrap my head around the LSD colored things you make. Personal preference, I guess... I like colors in harmony.
