Bare metal is tough to get right, I've never been totally happy with any BMF skin I've done. It would help a lot if AH supported specularity maps so you could make the metal bits shinier than the painted bits, but they don't.
I'd say the reflection effects on this skin look a bit overdone compared to what I'm seeing in the photos. I'd suggest toning down the darker elements of the effects to make the whole skin a bit lighter. Also the rivets could do with being a bit less visible than they are. The markings appear a bit fuzzy edged as well, which can happen if you resize them a lot. Perhaps you could remake them from drawn circles that are the right size. Same thing with the anti glare strip, the edge is a little blurry compared to the photo to my eyes.
