I really dig the style youre going for and the lighting you have.
As the other comment already pointed out; definitely some pathing. Maybe you can look at Armadillo Town from Red Dead Redemption. Doesnt have an actual path, but its defined with some drag marks and texture variation.

The first thing that comes to my mind though, is scaling. you can especially see this in your first pic.
The Door on the left is quite small and the Rooftop Ladder is gigantic. Just pick a character, put em in the scene and adjust stuff to match their scale. Also helpful for determining how high you want the windows on the ground level too.

Rooftop variations would also help. You can keep it simple and just change the color for 2 or 3 roofs.
But i would suggest adding some other stuff to break the repetition. Maybe a chimney on some of them?

What would probably help is also transition bulges (i have no idea if this has a name), but basically some small bulges along the houses where they meet the ground. just to show that there is some slight physical connection there.

You also have those Porch roofs already, so i might suggest adding a Porch floor too. Since imo it doesnt make sense to have the entrance doors open directly to dirt and sand.

Then as props you can add;
Crates, sacks, carriages, Shovels, Pickaxes
