I just want to share a site i found with all my fellow and budding artist.
Well technically it's a Japanese Blog that's adds different poses like everyday. It only shows the muscles and no skin, so that way you have a better grasp of anatomy.
The WIDE variety of poses and angles is great for refences, so i'm going to be unselfish and share it with yall !
i wish i could add a pic, but most of the site ( and all the pics anyway ) is kinda Flash based, allowing you to get a full 360 spin of your chosen pose, which is pretty awsome, and it features both men and women, so it's worth checking out.
Here's the Link : http://www.posemaniacs.com/blog/pose/
I'll add it to my links as well. have fun with it ! lol
