Cool. Sort of a deKooning process paint look. Have you considered not filling every inch of the canvas? Not saying there's anything wrong with this, but it might freshen things up to look at things like with a portrait approach = to take the inspiration of the landscape and concept kinds of interpretations and approaching it like a portrait -- same chops, just as if you were doing a vignette. That might be a springboard into other kinds of designs. I know it's fun for you to put on music and just paint and paint until it works, but even if you do that, you may want to try stripping out sections and laying a shape against a simple background.
Don't know whether it would work for you or not, but it's a thought to keep it succinct and from becoming like run-on sentences. It's not so much about laying over stuff, but more like deleting stuff. An analogy might be that of a writer who writes and writes until he seens what he's getting at and then cuts vast chunks out that was a matter of trying to zero in on what was ultimately stated in a few sentences.
Just a thought. In other words, go deeper.
