Low-key self portrait

My get-pushed partner, @summerfield gave me the challenge of a back-lit or low-key self portrait. This was one I really needed to do some learning on. I have a long way to go, but this is what I got.
Please give me some pointers, I'll take all the help I can get! Thanks for stopping by!
