Landscape as a big still life?

It occurred to me that I have been composing landscapes as though they were still lifes. I’ve been seeking shapes, piles of stuff, depth, different textures, selective lighting and so on.

Am I limiting my work by doing this? I’ve been told to follow more traditional compositions (e.g. Carlson), but I find those dull and predictable. Formulaic compositions lead to formulaic paintings, in my opinion. Any thoughts on whether I’m actually doing landscapes?
