Can it be possidable to make the Esper Terra into Cosmos from Dissidia?

And I was just giving my opinion of the sprite, regardless of who is using it?

I figured she would appreciate the constructive criticism. I think it'll vastly improve the entire sprite if she just changes the eye color to the darker gold (used in the hair already, doesn't even require adding a new color!). I'm not saying it's a bad sprite or trying to snipe at her or anything...
