I like the idea of these sci-fi under-suits which are like full-body underwear for your space suit, like a zero suit or plug suit etc.

proportions are not so grand but eh, I also DO LOVE drawing flat chested super model types.

Zwitter elf 1 is sort of recycled over Minhasil and will be fairly pale overall with a greyish suit with fairly dark limbs and flat, short boots, elf 2 I am not sure, light grey skin, patterned head shave, white suit, obviously an imposter (no PDA)
