Character Reference Background

I thought I would post a screenshot from a base mesh that I can open up in any paint program.
Then with Layers I can sketch or paint character to generally fit a reference mesh.
It gives me strong proportions to guide me while drawing and also makes my base mesh even more useful if I bring the new image back into Blender for a background image.

Feel free to save this image and try it for yourself.

Now I can quickly render a concept using a greyscale. This can work very fast depending on your skill with your paint program.
