looking good so far Poop, but I have a question for you.
Are you using a profile from Osprey's book and adapted it on the Ah skin?
If so, I discourage you from going on. You may have problems down the road where the homogeneity of the skin will look funky. When you will manually do the camo patern, you will not be able able to reproduce it exactly like on the profile view and it will show. Plus when you use a profile view, it takes a lot of colors out of the 256 available. it takes less colors when you paint it yourself.
On a side note, I would suggest that you would not waste your time to paint the plane. Your first step should be to paint the panel lines, the stripes and the outline of the camo. Then you will spend several hours to make countless adjustments to make the 2D skin match the 3D skin. Then you can paint. If you paint first, you will have to redo everything when you will notice that the wing/fuselage camo continuity is broken, or that the top inv stripe down't match the bottom one...
At those "junctions" that you will identify, make sure they have the same luminosity. Example would be the engine cowling. You do your fancy painting, then on the 3D model, you realise that the 2D skin of the cowling as a demarkation. its because each edge of the cowling 2D skin are too different and when they come together on the 3D skin, it shows.
So on your skin prep, make sure you identify the areas that are next to each other on the 3D model, but far appart on the 2D skin.
Hope that helps... oh and maybe you should do like me, wait for the new jug 3D model, so all your work will not be send to ... the pooper.
