Thanks for the kind words, Shadix and MrBragg! I am indeed still working on this, though I must admit that I only picked up last week where I left off last summer (so progress has been slow). That said, given that most of the polar landmasses will be glaciated, finishing this part shouldn't take too long (fingers crossed).

Here's something of a WIP-map with the glaciers thrown in:

Still tinkering a bit with the "Glacier gradient", but the basic idea is to use a similar elevation gradient as usual but with different colours to represent the extent of glaciation. Though in this map the thickness of the ice isn't there yet, still working on the underlying topography (I'll probably skimp on the detail a lot though, when it comes to the glaciated areas).
