You can get some detail carving blue or pink insulation foam, but regular white polystyrene doesn't carve all that well. Whatever you choose, add some water to PVA glue to water it down a bit and brush on a layer to give it more strength before painting. (the more layers of glue, the stronger, but also less detail.) Use wood PVA glue if you can find it.
