I recently ran a painting class that was focused around painting busts. I spent between four and five hours on each of these models. They were examples of different colour schemes I chose, warm, cool and secondary colours.

Lots of fun. Great model to paint.

It's also interesting painting the same model several times. Gives you and appreciation for a lot of the little things you can change to add more character.

Appreciate any feedback!
Cheers
