Hi Chip, nice looking 109
An unusual colour scheme for a late war 109, is it as per the kit instructions?
Did you do the weathering on the underside over a gloss coat or after the matt coat was on?
The top side looks a little err........."frosted", I think this might be caused by to heavy a matt coat or possibly having the airbrush (assuming you used an airbrush) to far away, while spraying.
I might be wrong but I think I can see the exterior colour on the inside of the starboard canopy framing? If you paint the framing the interior colour first, RLM 66 in this case, then the exterior colour, the interior colour will show through the clear part on the inside. One other benifit of doing this is that the canopy frames wont appear to be lighter than the fuselage. This is a consiqunce of light shinning through the thinly applied paint on the clear plastic.
None of this is ment as criticism, you still heve a very fine looking 109
