Used: Photoshop CS6, mouse

If you have any ideas, tips or CnC please let me know.
Also the armor is just an experiment to see how it looks, if you want I could post the version without it.

To Do:
Add more depth.

I really think you have a good base with the main part of the face. The shading and depth needs a bit of work, might need some darker tones to really bring out the sag of the skin under the eyes. With having said that, I think you have a great base for a great looking head!

Thank you! Also you are right I might have to darken it a bit to give it more depth.

Added a wip for the armor still trying to figure out how to darken it under the eyes without messing the rest up too much.
