Hi Kate — Hx Works here. Here is a self-initiated 12-frame character walk with transparent PNGs and editable SVG frames: https://github.com/hxsworrk-lab/character-walk-study
The animation is code-authored, with Python/Pillow PNG exports. I understand your brief covers the astronaut design plus idle, walk, mining and building/tool-use; this example demonstrates the walk only. Would this stylised look suit the project, and how many movement directions do you need?
My reference rate is US$25/hour. Total price, timing, source format and rights would be agreed for the full scope before work starts. Public or redacted style references are welcome.
