Dawnbringer Riven should have brunette hair like Leona
While overall the skin is pretty good, the steel blue hair and purple arm make her look like a cool and calm fighter - it doesn't scream "light" or "dawn". She looks more like a Duskbringer: http://imgur.com/a/xzcih
Riven can learn a thing or two from the OG Dawnbringer herself:
Now THIS girl looks like she's bringing dawn. The warm colors - gold/orange/yellow/brunette completely take over as the highlight. Even her eyes and make up explode with warm colors. The purple just provides a nice contrast but doesn't overpower the dawnness.
It should be the same with Dawnbringer Riven - let the warm gold/orange/yellow/brunette colors take over instead of blue and purple on her hair, face, shoulder, and eyes.
