Wow!
That's looking more convincing every version.
I keep thinking the water looks like it just flooded from snowmelt or too much rain, but I don't think that is your intention. Most of those tundra ponds have some kind of plant at the interface of the water and the land, and the bottom is just a very dark decomposed plant goo. I wonder, can you mask the ponds so the the populations are different types or species under water and the edge can be a zone of distribution for clumps of bushes?
These are certainly not criticisms, you have just got me thinking and imagining more detail. Like I said earlier this summer, I wish I could do this kind of work. My system is just too slow for big populations.
cheers,
