Alright, I tried a displacement map on the names, and I didn't really get the look I was aiming for. I'm going to play around with things a bit, but I'm probably going to blur things a bit and leave it at that. I'm considering this one "done" except for naming.
But I'm working on my next idea related to this style. I'm finding that the "Grain Merge" Layer mode does a pretty good job of making things look a bit more painted/inked on, attached is a little test piece I put together to see how it would look with some hand-drawn elements. I think from now on I'll be doing more of the mountain/forest type stuff by hand.
