Cosmic Xayah skin critique/suggestion..
I'm too lazy to post photos so I shall woo you with the power of words. (edit: found a photo)
So in Xayah's cosmic skin, similar to how Kassadin's visuals work, her wings are a glimpse into a starry otherworldly realm. Therein lies my critique: the background layer is too dark and there are barely any stars or other features to see. I think it would be much more interesting if the background you see through Xayah's wings was more vibrant and had more interesting colors and big bright stars. Throw some purples and pinks into the mix and we're in business! As it is now, most of the time it just looks like she has dark blue wings.
(additional note if a Rioter reads this: in my truly humble opinion, I think the effect would be more pronounced if the background layer was static. The characters are moving around 90% of the time anyways, so there is no need for the background layer to be moving in addition to the champion. Pre-VU Kassadin is the perfect example of how cool the effect could be (minus the gaudy background used). It's as if you are looking at another world that exists just beyond this one. Consider it!)
Other than that, love the skin!
Whatdya think? :D
