Try to lighten your adjustment layers a bit.
I can see at the top where darkening and I assume, blue photo filters, made the building, the moon, and some of the clouds LQ.
Also, I would try and create a focal somehow. My eyes are drawn to both the moon and the tree roots because they're the brightest areas, when the focal should be just one of those, or maybe the guy.
Other than that, I like it.
KIU.
