Definitely you need second looks to grasp everything. I think it's important to remember that Ancaria is not a unidimensional world where the same tempo and feel is dominating, unlike Westeros or Middle Earth. Here we have happy places like Thylysium and Griffinborough, where you perfectly captured them with the palette, dark places such as Entruag and Hissil'Ta, where more somber tones work, and fantasy places such as Dyr-Laigh and the Dragon Sea archipelago, where sharp contrasts would do wonders to capture the fairytale idea, just like a HOMM classic. And boy it's a big canvas...
