It has got some potential, looks like a profile of a captured F4U I came across a few years back... A couple of creative tips for you - from one who has done more Corsair skins than I care to think of..
The panel & rivit lines, you might wish to reduce their transparency down, 20-30 percent even, and duplicate the layer, and make the duplicated layer white, also with the transperancy down - moved slightly (read 1 pixel difference) to create a 3d panel effect.
The F4U is a difficult one to get lookin right, it took me a while to get the effect quite right & perfect my own template... see below, might give you a bit of a idea of how I proceeded through my ventures into the wonderful world of the Corsair Pallete.
You may also wish to make more of a contrast in the camo scheme too, but thats just from what I reckon anyway.
Keep at it mate
1st - note the panel effect is similar to what you've got there;
2nd - note panel/rivet improvement, plus colouring and weathering improvement;
3rd - note further improvement on the Panels/Rivets, and weathering effects;
4th and final version, and perfected base template;
