@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.

@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)

The green and brown color palette is beautiful. The stones "look very clean" to me.

Maybe also add a very glow/radioactive green option on water (as well as smoke effect) to indicate severe poison/contaminated area.

Pipes Png ejecting water and without ejecting water (in diferent colors also) will be amazing <3

Welcome!

I also suffered a lot in this aesthetic aspect until i start to do something acceptable .

This tutorial https://www.youtube.com/watch?v=B8Fvz98lJ7Q&t=524s helped me a lot to practice this. Once you have mastered the "operation" of tracing, you can superimpose any image, and at that moment I used images from google maps for reference... and I still use it... a lot!

Cheers
