Rainbow Splash

I'm...not very good at naming things! ^_^;
She started off as G3 Rainbow Dash, with horribly frizzed hair and some stains I couldn't get out. She was supposed to be ocean themed, but without thinking, I painted goldfish >_>;
She was rehaired with daiquiri ice and mermaid. The difference in the two colors is very subtle and the camera doesn't show it well.

I know I could've done the paint smoother, but overall I'm pretty pleased with her. But still, I'd like to get a little constructive criticism that I can apply to future customs.
