@OwlishlyTaboo i have same perception of @Wyvern on #3.

When this situation happen to me - and is most part of the time, i adjust the proportion not by numbers but by visual (not zooming in), simple way: i select a mountain, hill etc already placed and compare with the new selected one.

When i get the "correct proportion" i continue mapping.

in last few weeks i start a new usual behaviour in those situations, i write on paper all main sizes (and color number used... plus you can add size/color records to background, medium ground and fore ground on map):

back ground middle ground (optional) fore ground (optional)

mountain : 0,5 color 35

hills : 0.4 color 37

tree : 0.35 XXX

city : XXXX XXX

This helps me remind fast witch size/color i use as base refference in a great size scenario.

Nice Work mate, keep on!

Cheers

1. when i added edge stripe image appears on back ground, so ive added some mountinas on Symbol Back sheet to hide those back lines from the hidden land.
2. not shure already what i like more in this example (i changed a little bit to make a test). i hidded the land behind the hils image, so only appears edge stripe effect (or not, then no need to place a hidden land)
3. on this is the another option, make a very thin land line, just to give some green.

its nice idea, but in this map i selected sea as first back ground to use at same time as sky and river.

Just added symbols and then a small portion of land on low border... i forgot to use edge stripes.

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