Here's a smooth version of the skeleton I use for ditigal art (same as hand drawn, but I'm too lazy to get a book, draw then scan.)
My regular lines are ridicously ugly because I don't use a tablet. Plus I've memorized how to do all the leg styles, so I don't do the guide for them.
This skeleton is based off of the one you use if drawing a horse, basically (I'm a horse person and thats one of the reasons I'm here).
Anyways, that looks really nice for a first attempt! The mane seems to be a bit flat, and the tail a bit too out, but the body looks nice, the back legs might be a bit too curvy though. The shading on the torso looks awesome too. :3
EDIT: The skeletons muzzel is off... dammit.
