Oh, and a modeling note, as well as tinting the side windows, painting the dome's clear plastic with a bit of thinned Tamiya transparent green acrylic model paint with a bit of transparent blue added is a way to represent that if dome window plastic is not already tinted. Airbrushing interior of clear part is preferred method for a smooth coat but hairy sticks can be used if you have sufficient skill there.
