Nothing too special, I just came up with some concepts for flare skins! Here's some art I made of them:
A firework, a party popper, a rocket, and a dragon. But why flare skins, you might wonder, since they're something you immediately light up and watch fly away? Well, these skins could also have their own special effects when you shoot them off! Here's some image edits to show those:
Firework
Party Popper
Rocket
Dragon
In general I think these would make neat skins for a pretty useful item, and I bet people having a skin for that item would make them use it more
