I quite love her design! The only thing I must say is that she looks like she'd be hard to draw over and over again, as is needed for a comic. However, if you think you can do it, then go ahead. I like the way the snowflakes are drawn - it makes it look a bit more realistic than the standard six-pointed star thing. On top of that, you gave her a low cut top without making her look overly sexualized, so props to that. This piece of art overall makes me want to know more about the character. The more I look, the more I discover, and I really like that.
