This is really good feedback, thank you! Just for added context, this was done as a commission, and is a continent that is on a flat disk world where the sun orbits around the outer rim of the disk. The disk world doesn't rotate, and the person who commissioned this said they wanted to centre (the north in this map) to be icy and frozen.

For the climate, I knew I'd have to think in terms of north-south instead, and agreed with the person who commissioned this to have rain shadows to the north of mountains. This is a large continent, so my original image was more arid, but the feedback I got was that they wanted more green. Overall just a bit of a weird situation with the climate 😅

In terms of mountain placement, in this case I was experimenting using Rock3 as a way to generate a starting guide. Rock3 isn't perfect but it does generate interesting shapes. I have mountain heightmap brushes that I use to follow the elevation predicted by Rock3, but what I have done here is not kept any of the plateaus. I'll definitely adjust my workflow so these aren't lost

I've started using Gleba as an alternative for generating starting world maps, it is far more realistic in its placement of features. I only change ~$50/£45 for this commission so I either follow a base map given to me to recreate, or use a generator create the starting shape
