Another thing I just noticed...
On the P-47, when the flaps are retracted, they fit flush up against the trailing edge of the wing skin, so the only transition should be a straight line, with no shading to simulate a rounded front edge of the flap. The aileron, on the other hand, should be shaded to simulate rounding, as you have it. I think the aileron shading is much too heavy.
Last, give us some different angles and bigger pictures so that we can see the details around the various parts of the plane.
