YaBoi's Elytra

Ever thought the Elytra looked bland but wanted something in-theme with actual real-life insect elytron? Well me too, and then I remembered that I could make resource packs and here we are. I even made it look like it's made of Purpur and Phantom Membrane :D

on an unrelated note, why do vanilla Elytra have such weird models?? like they're full on rectangular prisms but at least 3 sides have absolutely no textures??? it even renders the backface instead of having none like most models???????? wth mojang
