New Technique: Drawing over Reference

Well, this may not be new to most people, but it should be here as a note of the class.

Technique:

Find the image(s) reference.
Resize the image to fit the dimensions of the work.
Paste the resized image into the actual art work, and move to the correct location.
Free transform the image (Cntrl-T) to fine tune the image to the correct porportion, angle, etc.
Create a new layer over it, and make it white. Make the white layer less opaque, more translucent.
Create another layer and label it "Line Drawing', and being sketching over this layer.

I used the technique for my Dune kneeling guy.
