Hi, Kit;
Very moody colors, interesting in the distance.
Maybe crop everything from just left of the lone tree/bush that's now in the left center? That way the gap would pull one's eyes into the distant hills. As it is now, that lone tree seems to just act as a brake, and I can't get past it. Or maybe you wanted to focus on it: if so, maybe crop out the line of trees on the right?
Cheers,
Rick
