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.

my default crack is little diagonal. cause this i said i dont rotate the crack... just enlarge it.

On this tutorial, @Loopysue show how to improove the map color at the end of the creation.

Personally i feel more comfortable importing the final image on lightroom to retouch some colors.

I think buildings are still a bit lacking in the cities. Specific oriental, Greco-Roman, African and Meso-American buildings would be a great addition to the collection.

As for the floorplan, battlemap, dungeon:

Library, Church (more variety of statues and idols).

Loose items: Weapons and armor, robes, staffs, bows, etc.

More decorative elements for gardens and squares, flowers

Casino and gambling items

Ruins and rubble

Graves, tombstones, ruined temples, shrines

Image patches with different ground textures like Sue did in forest trail

Roots and vines

Rope bridge

Tents and huts

Ruined stairs

More floor symbols, whether sacred or cursed (circular, triangular, loose runes, etc.).

Craters

Sleeping bag

Luxury furniture

@Royal Scribe for the glow behind the volcano I created two sheets for use with planet symbols and used two planet images one in each sheet (to emit a round glow).

A planet with an orange outter glow with more blur and Another planet with the red outter glow with less blur (smaller radius sphere). The only mike schley isometric symbols are the market stalls, the statue and the rowboats near the bridge, all others are from overland.

Maybe this little tut is some help for you. (ive made others using mike schley also)

@Lee Talman you can create as many sheet terrain/land features or even sea as you want. I frequently use this feature to be able to superimpose effects. In this image you can see 3 new sheets: 2 of land effects (the ice is on top of the tundra, and the SEA LAKE to produce the lakes on the map using the "water" of the sea.

You can also calibrate the inner opacity (I usually use between 40 to 80%) so as not to have a "too harsh" effect, sometimes even with low opacity the effects can mix, sometimes causing a desired effect - there is no reference rule for me, I adjust as I go.

Once your new sheets are created, and when you select the new terrain/land features effect... sometimes the program "sends" you to the original sheet, so you need to check and sometimes change to the desired sheet. However, even doing this, sometimes it happens to me that the program insists and places "base" terrain/land features on the sheet.

So what you need to do is go to the "change features" button, select the effect and click ok, then you choose which sheet you want to send it to. Normally this selection is easier when "activate sheet effects" is turned off, because the edge is easy to select, when edge fade inner is activated, it is usually difficult for me to select the TERRAin sheet I want.

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.
