Way to go! Its great looking. I know metal shines, u might want to add some brighter white lines near the rivets and a big bright feathered line over the middle part of the wing with your brush tool wich gives it a shine.
check the picture below what i mean with the feathered line, the left upper wing has no feathered line the right upper wing has. ( i took a brown color so its easyer to notice.

Also what i do wich makes the skin look much more realistic IMO is adding a black feathered layer on the lower parts on the fuse and the undersides of the plane. I use this as a shadow and change the opacity untill it has the right depth.
Also the USAF marking looks a little blurred to me.
I would fly it when i ever get the chance to fly 38 tho!
EDIT: u might want to check the colors on the merge with the engine fuse and the wing. the engine fuse looks a little more greenish to me
