Wow... what an incredible effect that has... And the work on the border! Words are hard to find. What incredible work! And now, with the last images, we can see the extent of the work (done and still to be done). It's truly magnificent!
The choice of names is also very well thought out: it gives the whole card a poetic atmosphere, and that's fantastic!
It's fantastic!

PS: regarding the 'greenish' aspect of the icy zones, the last one with the blue tint is muche better... in my opinion, you could make it a bit more blue
