Old old old oil portrait

I was looking through an old pile of files on a hardisk, and came across this one. It must be 5 or 6 years old by now. But looking at it for the first time in years, I felt pretty good about it.

I feel like I have learned a lot since then, but I can't help feeling a little proud of myself. At this point, I had no formal training in traditional art whatsoever.
