You have got some great large scale displacements on your butte, I like it!
I'm not too fond of the colours to be honest, but may be I'm suffering from tunnelvision with regards to this topic, I always want to make them look like the ones in Monument Valley.
If you wouldn't mind I'd like to have a go with your .tgd and see if I can help you out with those stratified colours etc.?
Looks like you have been using the old-school bitmap trick back from the TG0.9x days?
