She looks pretty cool. I do think she should've been hovering in neutral and when moving back and forward, but otherwise the presentation of the character is very well done. She's like mother nature, having the four elements at her disposal, and that's nice and all... but I would've preferred if she was more focused on plants and such ala Poison Ivy. Of course we haven't seen everything yet, but it was a bit all over the place, imo.
Also, her intro dialogue with Jade reminded me of the Kitana/Sindel scene in MK Annihilation. She could just as well have said "Too bad YOU... will DIE!" to Jade. XD
