forgot a few things, you can have a different ortho for individual part for better detail such as for the hands and feet. While I am lacking on the drawing skills I am quite familiar with turning ortho drawings into 3d models and it is something that I have been thinking about getting into for 3d printing of various characters and such. With a ref sheet like this I can make a 3d model and pose it even put hinges in the joints to make action figure type things. Still practicing with my new program but making leaps and bounds, main issue I have been having is having something to practice on. hoping to have some finished products to show off in the near future.

The figure screen shots are from 3D Coat and from my reading of the EULA I can re-purpose them in this manner
