Any idea on how to reproduce this?

Saw this and was supper inspired, I’ve learned to make patches of 4/1 weave and that’s about it right now. But I’d like to start this as my first big project. Only problem is I really am not sure how to go about making, or following a pattern when it comes to chainmail. Is it like a knitting pattern, or a clothing pattern? Anyways, any help on how you think they did this, or what I can do to get started would be AMAZING, thanks ❤️
