I like her. She looks perky. And She is your character soI think that in the end you should really make her look exactly how YOU want. She looks really happy, alive and bubbly on this. However I do personally prefer her looking more like a real woman. considering her body type that somehow really seems to suit her. But I guess this look is aiming for childish, because she got her tongue sticking out and all So if that's what you want to portray in her you're going the right way. I'm just not sure which kind of look you want to achieve. Either way it's a nice design
