It's a relatively small surface to really notice the textured effect. Maybe if you print the map in a large size, it will be noticeable.

I hope you have some coffee left over so you can drink it while you recover :)

I will try to make a Glacier cave.

This huge vertical wall reminds me of the majestic Perito Moreno glacier.

A wonderful combination of symbols and creativity.

Crater is from Sue's darkland overland

As for the cave, I deliberately made it relatively discreet. I tried to replicate as closely as possible the original external environment described on the Dungeon map that exists there.

The Origin of the Circle of Belthara

A figure dressed in a black cloak, of unknown origin and time, appeared in the Vale shortly after the southern refugees' pact with the entities of the Vale. Known only as Belthara, she carried glowing fragments of an ancient comet, which she buried in five specific locations throughout the forest. Within a few days, the monoliths sprouted, forming the circle.

The Surroundings of the Monoliths

The stone blocks that make up the Circle of Belthara are hewn from rough rock, a deep reddish-black, marked by veins of crystallized amber that seem to pulse with dormant energy. Covered in lichen, these stones react subtly to the magical touch of the Bearers, vibrating in soft tones or exuding arcane heat. The circle stands in a rough clearing where vegetation does not grow. Beyond the clearing, the Forest of Ukra Dor stretches out, silent and watchful.

The Activation Ritual

Only trained ones can activate the circle. In unison, they chant ancient chants inherited from the Core of Sap. Each note attunes to a monolith, which glows a distinct color. When all five glow in unison, a veil of multicolored light condenses in the center. Through it, Stargazers can travel to distant places, connected by ancient pacts with the Vale.

The Return to the Vale

Exhausted and sometimes wounded, Bearers return to the Circle of Belthara through the same arcane paths. The surrounding forest recognizes their crystalline cores and does not attack them—instead, it makes way. Their return is marked by reverent silence.

Or they come out from inside and end up, sometimes badly, outside lol.

As for the cave, I hope this icon can be used as an entrance and is versatile in slopes and mountains with or without snow.

Perhaps working with the drawing vertically will help the sensation of depth more, since you can change the mountains behind them on the X and Y axis.

A little bit of clouds always helps with the sensation of Landscape.

In the right corner of the table, the mesa line is crossing the cliff, you can put the cliff in front of the mesa (if they are on the same sheet) or even use trees to hide this irregularity (normally one of my most used resources for imperfections).

p.s.: Whenever you are going to make a "multi level landscape" keep in mind that darker colors usually give the impression of lower parts, and lighter colors give the impression of higher regions.
