Okay, I pulled out the rock area, selected it and stroked it with Gimp's default pencil sketch#2 brush with a .4 jitter. I used the selection to cut out the strokes that fell within the tunnels and set the whole layer to overlay. Got this result:
Similarly with the same procedure and the galaxy brush with a jitter of .7 and reduced spacing, gives this:
Both quite nice actually. I'm not sure I'll keep them, but its a technique I'll work with in the future I think.
Cool! Glad you liked it. Like I said, I used it on a coastline one day. Here is the original:Originally Posted by torstan

And the one with more stuff done and where I stroked the coastline:

I know had I had the jitter set really high, but I am not sure what tool I used, I "think" I used the smear tool. I did this on a copy of the land layer, set it to overlay or soft light(I think??) and put it between the water layer and the land layer in a nice sandwich. I ended up really liking the wispy effect it made with the lighter shallows quite a bit, so will be playing with that technique some more.

The galaxy brush one is really cool, but the pencil one at the top ROCKS.

Haven't been keeping up like I should. Those maps absolutely rock Torstan! I love to watch how a map evolves with each iteration.
I actually prefer the one done with the galaxy brush (though both are really good), the pencil mark one tend to distract my eyes to much. But that's just me

As a quick suggestion - instead of stroking the selection, turn the selection into a path and stroke the path.
I have discovered that this seems to give significantly better results. (The conversion to a path does some bezier interpolations around the selection that seem to prevent some "jaggie" artifacts that stroking a selection seems to have.) Now this might not matter when the jitter is high, but try it and see if there is a difference.

Nifty advice. I think I'll try that myself soon.
Ah... yea, thats what I meant and left out. I create a path so I have it for later use in case I need it for something else I don't have to go try to get the selection right again. Did not know about some of the problems of just stroking the raw selection though, so thats good to know.

Good tip. Sadly the xcf is now on a defunct laptop so, barring resurrection, this WIP is no more. I'll have a shot at those tips over the weekend when I have roped in the work computer to mapping duty.
make good use of your dropbox account....
