Wheeee, drawing from reference! Fastest way to get better, draw what you see, either from life or from reference, it's always a good exercise!
Anyway, we've got some deer, some foals (Arab foals...come on, I'm trying to work out the best way to draw unicorn faces, of course I'm gonna choose my favorite breed of horses to look at!), and drawings of the unicorn from the Last Unicorn!
Also Sonic at the bottom, and the design for the cutie mark of a pony I'm playing in a Pathfinder game! Good fun!
Basically, I can feel how unicorn's heads are in my head, but putting them on paper is a different matter. It's literally drawing something by feel, not by sight. Heh, maybe I should try sculpting!
