Hi there,
This sounds like a really exciting project and I would love to be a part of it.
I am a quick working, adaptable artist and I work in many different styles. I have some example work on my profile, and although I haven't got any animation examples for you, I have done a little animation in game development jams and in personal projects, and I could very easily cater to the style that you are looking for. This wouldn't take me long at all, and I would work hard to achieve the results you desire.
Hope to hear from you soon.
Thanks,
Mayenna
