In the last round of creating textures, I decided to add a tree into the sand texture (I usually add them on top of dried texture for the tree silhouette pieces). Of course they start with the background.
Not sure I like this method as it adds hard boundaries to the edges of the tree.
There are a few elements I'm not excited about, but a lot I do like. Overall, I learned a lot on this piece and am happy with the final results.
...and some final adjustments
