Never noticed on your earliers P-47 skins, but there shouldn't be any shading along the leading edge of the flap. The flaps fit flush against the upper wing skin, and thus, should merely have a line showing the transition. Also, I can't tell from the resolution, but you shouldn't have a trim tab on the right aileron if you do. The P-47 only had an adjustable trim tab on the left aileron.
I'll go with either TB's or Wrongway's recommendation for the skin. PTO Jugs are too scarce.
