Tamiya red brown on. Will proceed with postshading with whatever yellows,browns and everything in between i got handy before masking for the 3rd color.

You can see there are two steps with the masking; first i’ve used electricians tape because it’s flexible, i cut long thin strips and then stretched the tape almost to the point of bursting which makes it easier to bend while on the surface which formed the outlines, then the inner sections are filled with tamiya masking tape: 2.5hours of work. i will have to repeat this entire process twice more… oh the horror, the horror!
