Stormlight Archive - Parshendi art form

Meet Arkto! Arc-too, like R2-D2 :D She, or they, are how I imagine the Listener Art Form. So far we have seen a boat ton of War Form, and I thought, that’s boring. They don’t do much beyond smash and break. The Art(isan) Form, now that’s more fun, because they can do a lot more stuff!
.
But what do they look like, if not in full carapace armor of War Form? I don’t want them to look like human. That make no sense for a species that evolved on another, crustacean-based planet! But the more I add non-human parts, the more they look animalistic instead of civilized. Wait! I know! 4 arms! I often wish I have 4 arms when making stuff. This way, Art Form Listeners will rely less on assistants, and be free to just express their art!
.
For a world that is so wet and stormy, I figure most of their art would be water resistant like stone sculpture, oil paint, and since they aren’t short on crem, ceramics. You know what Art Form would play on a piano if they have 4 arms? Woogie Boogie.
.
And of course they wear skyeel leather as part of their clothing. I don’t see chull shells make comfortable anything other than Klompen :P
