I think this is potentially fantastic. The wisp of cloud upper left balances beautifully with the forms of the trees, so your negative space in the sky isn't flat, it's perfectly subtle, to my eye. I like the grasses at the bottom, giving another field of almost-negative-space here to echo the sky. The trees are really fortuitously placed.
The only quibble I have is that there seems to be a lot of local contrast in the trees, and in the small size we see online it's really visually chaotic and not quite pleasant to look at. It's possible that in a larger size this would be perfectly beautiful, but I feel like it's also possible you've leaned on a 'sharpen' control a little too hard for my taste.
If the trees were more of a coherent mass, and less visually busy, then you've got a lovely abstract with two spaces (sky/grass) and some simple forms (trees/cloud) laid gently on them. The forms resolve in to real objects when you look a second more, and that's a nice reward.
Honestly, this is a photo that I think would benefit from some blurring. If it were rendered as some sort of Talbot-era paper negative salt print thing, I think it would be shockingly fantastic.
