I really like the way Katja looks now, she's unique and pretty. The new look is gorgeous, but it doesn't have the jazz that fits Katja's personality. I like how her marking is yellow and I like her fur color, but the gray isn't saying "Hey, it's Katja!!" to me. Nor is the long, sideswept bangs. :D
But change is good, I've changed my characters around a lot myself. :P
