Skin Idea: Cosmic Reaver Evelynn

I'm a crap artist, but the general idea would be:

Invisible Form: imagine Aurelion Sol for a second - now think of how the transparency works for his midsection leading to his tail. She would be something like that

Visible Form: white hair; pale blue eyes; star-filled body, much like Kassadin's Cosmic Reaver form

Q: Opens up a rift to another dimension. As the rift ripple across the ground, comets shoot up and strike anything in their path.

W: Eve's hair wisps out like smoke. As she bursts into a sprint, constellations form in the path behind her

E: Impacts with her claws release clouds of stardust around her character. Stardust would draw inspiration from actual stardust seen in space: example

R: Eve summons a galaxy upon the ground, in which the galaxy spins quickly and tails migrate upward, smacking opponents.

Final Thoughts: The skin would need a custom model, custom particles and sound effects that are much different than her current model. I'm thinking Cosmic Reaver Eve instead of Star Guardian because if Eve's current skins and lore are any indicator, she's more of a "plundering forager" than a guardian of any sort. Also, in her lore, no one knows where she's from - they guess the Shadow Isles - but rumors are always circulating. And for icing on the cake, there are her quotes:

"Shadows beckon." "From the darkness." "Into the night!" "The night is my veil."

And space is pretty dark last I heard.
