The "ribs" on the control surfaces are far too prominent. They would also be a silver doped shade of paint, instead of metal (assuming they're fabric covered, which I think is correct off the top of my head).
I also think you need to redo the blue. It looks more like a light blue spraying of paint that is wearing away. It doesn't convey "bare metal" to me. This is one area VERY hard to get right, and it took me several skins to get to where I felt I was happy with a bare metal result.
Kev did a nice comparison graphics showing some of the steps he used to build the BMF layers up. Does anbody have the link for that one? It could be useful here. Generally speaking you have to bake on the reflection map. You have to paint the metal as if it's reflecting different things along the different curves of the fuselage/wings. Some "bulging" or whatever term you prefer can also add a little pop to the individual panels themselves.
As an after thought, I'm not convinced by the port-side cowling drips, but the BMF to me would be the more important thing to work on.
Look at some of the previous BMF screenshots you showed. Add just a bit of that (maybe 10%), and it may help a lot.
