I did a Tails painting a while back for extra credit in Physics class ;)… my reference was nothing but a wee tiny Sonic 3 sprite. Some of you might recognize this Tails rendition from Sonic 3/S&K! I hope you appreciate that it was referenced from such a small sprite.

Clickity-click the smaller Tails pic to go to the full-sized painting. Done with Photoshop + Wacom Intuos3 + Love.
