the stairs were the easiest solution considering that isometric cities do not have stairs (wood/stone). Perhaps the easiest thing for Sue Richard Darkland's Cliffs to match with the Temple of Bones (@EukalyptusNow ) stairs was the fact that they shared the similar color tone.

The dirty roads are from mike schley isometric city with edge fade inner and less inner opacity %. I thought about using barrels to decorate the markets, but proportionally they seemed too small and would pollute the image more than they would add detail value, so they were discarded.

Maybe you can use thatch building + wood and gate fence from Isometric City Schley + Horses from Mike Schley Overland style.

Make a Terrain SHEET to the stable where you put more MUD/Earth Terrain style to give the "dirty look" on floor.

I typically use multiple TERRAIN overlays on floors whether they be dirt, grass, bricks, rocks, etc.

I just select a color similar to some other bitmap fill from TERRAIN to, on the one hand, break with the visual repetition of the Bitmap on a large scale, as well... for example in the wood of the inn - where a lighter TERRAIN (in this case I think it was earth or mud) which shows - in the most traveled places the effect of wear and tear. I have even used some Sheets (created) including on top of SYMBOLS.

For these effects, I normally use EDGE FADE INNER between 40 to 90% and with a lot of Edge Width proportional to the size of the map.

Here an Example

i also turn off ALL my "Restrict to map border" options where im working.

Rivers, roads, land mass, default terrain etc.

For me its more easy and fast to work. Then i clear outside map using collarw comand.

Control + Shift allow you to smooth rotate and angle as you want in visual mode.
