First impression is this could be a real good photo if it wasn't so dark on the left side. On technical merit though it is really good. We all know a plane is a hrd place to photo. This is a good self portrait under those conditions. Nice DOF, nice focus. The detail in the skin is great. Composition is also good. The only problem I see with the background is that there are some marks on the wall behind you that makes me wonder what it is and kinda takes my attention away from your subject.
