First, congrats on the new baby!
Second, that looks like a really beautiful interior! Geez, I'll be really interested to see how the painting goes; that looks like its gonna be a chore all sqeezed in there!
Having worked with some resin interiors, I would have recommended that you try to lay in the bottom-most pieces, and then glue in the other parts after painting. I hope you can adequately cover all the surface! Then again, if it's only gonna be possible to look down the hatch, it mat be OK. Just be sure that when ou airbrush the interior, make sure that you direct the spray from the direction of the primary perspective, ie, from the direction that you will be looking in--that way you can be sure hat the paint will have hit what you will be lookng at!
Can't wait to see it! Might wanna adjust the yellow balance in your photos though?
