If I am not mistaken, this might have been the first stab at designing Poison Ivy, so as you can see, it pretty much went through without any major changes... initially, the idea I had is that her hair would always move like it was underwater... moving slowly and weightless ... also with the idea is that she's so beautiful and actually 'toxic', that just being around her would begin to poison you and send you on a bad trip.
The concept of Ivy for me is simple, she's supposed to be a greek goddess of temptation, or a Mermaid of sorts, she attracts you with her looks, then kills you!
... AND with that said, the modelers and animators at Rocksteady made her sexy as hell!
I think I liked this design a little too much. I was actually hesitant to face her because I knew once I beat her I'd never get to see her in the game again XD.
I never thought i'd see a real deal concept artist from something i knew on DA. Great to see that you're on here. The Ivy concept was something me and my friends talked about for weeks after playing the game. Awesome job and i love being able to read about your influences for her design.
