I like the squigglies in this sort of processing. There was a program I tried in G'MIC that did this sort of thing, but the results were very size dependent ... so it was hard to gague what results might be from thumbnail. It's been on my mind to investigate further so that I can see what dimension of picture give what results. ( which had no relation to the little thumbnail preview)
Processed beautiful, you haven't had rain for a while?
