This is very impressive, amazing work! The fact you did this in only two days is mind-boggling

Glad the author liked your interpretation too, and your creation of brushes using real terrain data worked really well. May I ask which mountain ranges you took inspiration from/sampled for the brushes?

I also love the attention to detail with the dunes of the desert, but like Kellerica said with the forests I think the brush size may need to be larger or more varied as its largely the same pattern.

Really liking the gradual descent in the sea with its terrain features gives a great illusion of continental shelves too Brilliant work
