I have a couple of things you could fix. I did some 110C skins (They're similar) so I know what you need to look out for:
1) the camo stretches too far on the belly of the tail boom. Bring the camo up a bit (shorten it) so this isn't so prominent.
2) You need to find the part on the nose where the camo is going to end and make a border, rather than paint all the way down and then have the "chin" piece be light blue.
3) The inboard exhaust stacks point down, not up (the streaks would be underneath)
4) the underside is almost white. It needs to be darker. It also needs to be dirtier!! Much MUCH dirtier! Around the engine nacelles, the gear doors, the radiator housings, the nose, the belly (oil etc) the tail (dirt) -- muck it up!!! They kept their 109s clean but they let their 110s go to pot, it seems.
5) you can look for the area on the bmp that has the gun pack (it might be on there) -- if you can find it repaint the gunpack to be the same color as the belly.
I like the colors, though. It looks nice. Do some fine tuning and I'd fly it myself, in the main!
