Yeah, it's a great character concept! It's really pretty surprising no one has used Pandora in comics before. The gadfly characterisation is an interesting choice. It has an element of the naive mischief-maker that fits in quite well with the mythological character.
And, of course, the design is great and appropriate. And I think the main image of her is one of your best from these character cards -- love the lighting!
Kirby himself would be green with envy over not coming up with this himself! I really love the character and concept. Of course, it doesn't hurt that she's sexy as can be either. Awesome!
