Realistic 3D Animation: Nature and Futurism

I am looking to create a 3-5 minute 3D animated video as part of a short conceptual film I’m working on. I would like to create a digital avatar and animate it doing a sequence of dance moves on a repetitive loop. I am envisioning the avatar dancing on/ in various architectural structures, either floating in white space or on the ground. For the structures that are on the ground, I would like it to be surrounded by a vast, dirt landscape, with a few thin trees. I would also like it to feel as if there is a camera flying around the structures, capturing the avatar from various vantage points. I am interested in a video game kind of aesthetic. I have attached sketches of what I have described.

Key Requirements:
- Must create a 3D animation, emphasising on realism.
- Incorporate elements of both nature and futurism into the video.


Ideal Skills:
- 3D Animation
- Realistic Rendering
- Futuristic Design
- Nature Aesthetics
