First picture: Entrance looks cool, pathing on the right of it too, but mayby a but to much different groundtypes, to few grastufts, nature, to much gravel, nature should be putted into groups.
Second picture: like it how you've done it with the mountains, the difference of the walls, and the coffins, but here and there could be more difference of interior types, ground types and keep it to just one roof (the yalahar roof in my opinion), mayby plant some wall plants, more of the dried grass (see n-e of the picture) and some red stones.
Ideas, improvements, like it as it is? Please give constructive feedback:
Sorry for spamming this amount of pictures of small pieces, asap I have created "my" style, I will stop posting pictures of the start of the city xD!
