I got a bit more done today...
I splattered the tiles with some wood filler and flattened it all out with a trowel.

After about an hour later, I washed the whole thing with a thinned coat of paint, and that looks like this (above and below)...

Lastly, I did a bit a dry-brushing. Lightly all over and a little heavier around the rocky areas..


Still more to do, but that's enough for today............
THANKS!
