I thought I'd have a go at doing my own displacements other than relying on other people's clips & using World Machine. I did use World Machine for the base canyon, but it's unrecognisable now & I think it turned out pretty good.

				Very cool. I like the detail. The trees seem a little out of place to me, for a creek bed, that may suffer flooding and wash away most permeant vegetation.
