You're right about the colour:

I just hadn't done the "stains" yet. I still need to reinforce the shading as it looks too flat. Some stencilling, the squadron logo and other things are also missing. Lots of other things to do as well, including the shading for the canvas.
I'm using an excellent walkaround from the Air Warfare Forum as a basis. I'll be making more when this first model is finished. Any ideas or requests welcome.

BTW, Santynus, what do you think of the panel lines? I've tried a new technique here: I drew the panel line in 1px black, with opacity down to 30-40%. I then duplicated the layer, set it under and called it "white lines". I then inverted the colours to have them white, and moved the whole layer 1px down and 1 px right. I find this gives more depth to the panel lines. The downside is that one has to erase the white lines in the places where there should be no light reflection.
