If thats a first skin, you have a bright future skinning planes in AH!
Looks great!
The only thing I'd try is lessening the opacity of the light panel lines, so the over all appearance is one of dark panel lines rather than light-colored ones. Compare the panel lines in the first to images above to see what I'm talking about - the photo has dark panel lines, but in the screenshot, the light panel lines are very visible.
Another tip is to use the 'outer glow' feature on the panel lines to give sort of a dirty, weathered appearance around the panel joints. I use 30% or so noise, and adjust the opacity for a subtle effect.
Great job!
