I may or may not be colouring these and mayor may not be using one or the other as dress-up game bases [which I maybe taking a backwards approach to turn them into vector shapes allegedly to make this easier]
But it is Hush and hir sibling Azul; Azul and zir sister Hush; kids generation 3 or something.

I still may go back and draw better prostheses[?], as these were done at something of a rush. One thing I did want was to give them prosthetic limbs that were relative to their accessibility [being young and liable to outgrow them, being lower-to-lower-middle class], but mostly it came to crunch time and I just gave them rough approximations of other prosthetic limbs without getting specific about it. Which I kind of regret.
