Hunter,
First off the construction looks really nice and the pilot looks great too! I've never tried figure painting myself so my hat's off to you!
As far as the colors, I'd have to agree with Brandon RLM 74/75 over 76. From what I can see in the instructions you would use the smaller aircraft picture (lower left corner) to layout you main camo, this one calls out RLM 74/75 for the topside, and then overspray that with the white. As far as the RLM 76 for underside, I usually use Tamiya Light Blue and lighten it with some white as I think it's too blue. I have been playing around with adding some light gray to the mixture as well as RLM 76 sometimes has a more gray apperance.
Keep up the great work!
