Painting DF Dwarven Forge as a standard dungeon

SO I started out with painting my DF tiles with the full 4 step process from Stefan's video(minus the random earth stone brick) , and then compared the pre-painted tiles I got.  I think I was in the unique position as I got unpainted base sets and some of my addons painted.... I think a lot of people went all painted or all unpainted(exect a CoS set) or if some did get the painted addons, they didn't get the set of 4 pokorny paints like I did.

So once I was done painting the 1st batch I did - I compared it to the DF factory painted, and I realized a couple of things.

I painted the right and left tiles - middle tile is factory painted - notice how much better the earth stone looks as a dry brush - doesn't stick out so much.

1. factory painted looks like it used 2 steps, not 4
2. the drybrush for the factory painted didn't match any of the 4 bottles of pokorny paints(this is why I say it looks like not a lot of people got both painted and unpainted, and the set of paints - or this would have been noticed)
3. the factory painted with 2 steps still looks great, so no need to do 4 steps..... so

I started doing the tiles with just a drybrush of stone edge which was the closest color to the factory dry brush.  I think they turned out great with just this(and saves a lot of time).

But then I also figured out something great.  Instead of the earth stone painted heavy on a single stone.  I used it as a dry brush for random sections of wall - it looks great this way and really gives the wall that old timey "lived" in look like a real old dungeon.

Also for my brushing - I varied the pressure and the wetness to give the dungeon a really variable look, so its not uniform.

I am also going to be adding some random green highlights for mold/algae, and some reddish highlights for old blood.

but you get a great looking dungeon with:
1. drybrush of stone edge everywhere
2. hits of earth stone randomly
