Oh, i really like this picture :) The horse muscles are great and your colouring very effective... but let me give you a piece of advice, dont do that during biology classes (nor during other classes ofc) ;) Hehe, teacher talking here :P

So pretty and very interesting style! :D

I love the shading on this. Sort of pop art effect to it, but it defines the muscles very well. I also like the texture of the... er, ankle extensions, whatever they may be, and the shading on the mane and tail are fantastic. And that simple little addition of green in the background adds just enough to make it complete. Very nicely done. This picture really jumps off the screen. Oh, and I love the style of the legs. The separated muscles and raised ankle bone are very catching.

really cool picture. I like the way yyou drew the "corners" and how you colored it :D

Woah, very unique hind legs! I've never seen a character with knees like that :P I absolutely lovvve the way his feathers flow around his hooves. He looks very different ;D
