All-star Diana Skin

Mainly I'm just asking a question that I'm hoping someone who knows the answer (Rioter) will answer. Basically I'm wondering what the style of the All-star Diana Skin will be. I know it will be either fire or ice, but the main thing I'm curious about is whether it will be the more realistic style like most other E-sport skins, or will it be more fantasy like Forest Fire Zyra? Personally, I'd prefer a more fantasy style, but I'd just sort of like to know.

Thanks
