In the overview you begin to give commentary (i.e. “at first it seems a jumbled mess…”)
I'd rather stick to describing it – what it constitutes or tells.
Worth noting a bit more about who the Walbiri are. Do you quite understand what Dreamtime means? I think it's pretty important; check this out: http://www.aboriginalart.com.au/culture/dreamtime2.html

There are other maps out there: https://www.aboriginalart.com.au/culture/dreamtime3.html
The key idea seems to be its a conception of the universe that maps religious concepts onto the present landscape – so that where we are today is also (on another plane) the space of creation, sacred, etc.
