i love it! However the teams are unfair Zekrom's side has a lot better pokemon such as Kyurem, Zoroark, and 2 starters. I think you should think about it a little more. Don't take offenses to this please, it's just friendly criticism
When I designed what everyone wears I did it with their prefferences in mind. And with Hilda I went with what she'd hate, and the only likeing I could see her having for that dress is that it's short. Basing it on her game design. I think she'd preffer more comfortable clothing that allow her to move more easily. Having the front of the dress be so short allows for that.
