What is Overpainting and Photobashing?

Hey all, had a change of plans for today. Instead of delving into master studies, I started my morning off with a cup of hot chocolate, warm breakfast and the second episode of Art Cafe. This episode featured Anthony Jones and Dan LuVisi  and covered the topics of Painting, References, and Photobashing. What is Art Cafe? I'll provide the video I watched this morning below.

Having watched this, I decided to change up my direction for today's artwork. It gets a little stale when doing master studies, so I broke it up with my first attempt at an over-paint. Now if you've watched the video above, you'll understand that this kind of "cheatyness" is fair when used well. Using it well means having a strong understanding of the basics, value, perspective, color theory, shape lingo, etc. At the moment, I'm not there, but it didn't stop be from playing around!

The below painting did use a photo to start with, funny enough I stared at it for a good minute before being "okay" with working on it. I'm very happy with the outcome, completely changed the values and hue from the original picture let alone hair and other elements.

Was a ton of fun, however I can tell I'm not quite yet ready for photobashing / overpainting.
