Death Blossom Kha'Zix looks significantly less pretty and imposing when evolved.

The skin unevolved looks fantastic, the color palette is excellent and it does a great job of being threatening by how beautiful yet dangerous it appears, like the skin's name suggests. However, the evolved form looks dull and erratic- the brown is terrible to look at, and the color palette has no cohesiveness. Brown, blue, dark green, orange yellow, red, and light green don't make for a pretty picture in this case, and the skin demands to be pretty to look like a threat. If the same colors are to stay they definitely need to be brighter and more lively. I love the concept but if the evolved form stays in it's current state I can see myself never evolving R to preserve it's elegance :P
