look closely at the lighter green lines (above) which I didn't draw with enough patience. You can draw with the necessary patience or "Hide" the flaws with another icon.

Keep in mind that deeper colors on the bottom and lighter colors on top when choosing your land features help with the feeling of depth.

In Sue Richards' annual Darklands you will, in my opinion, find the best solution to this situation. Since unfortunately other styles do not have, like this, "north-oriented" cliffs.

As you did with land features on the map, you will need a lot of patience to cover the finer lines with the land feature you choose.

Maybe this video will help something. For me, he was absolutely essential.

Hy @Loopysue thanks!

Using Adobe Lightroom, above and below I used graduated filter to darken by lowering the exposure.

in the middle - the mill and in some houses I used the radial filter to increase the exposure and "draw attention" to the buildings.

in the end, I increased the shadows in the corners using circular vignette.
