You really did a good piece of art for only an hour's effort. I'd increase the cheek highlights very slightly, with a few more shadows in the background/rear areas of the face towards the hair, which is has just enough of the right color scheme (I like the elements of charcoal grey hair strands amongst the black hairs); the piercings need just a few more gleaming highlights. The eyes need a just little more persona in them to further enhance their thoughtful look. The eyes really do show how intelligent this character is in nature. Other than those, this is a very thoughtful work- it makes me think of Captain Jack Sparrow in certain ways.
