I think Donald is pretty much spot on.
The colors and the trees are not enough to carry this image. It is dying for something of interest in the foreground...............a large rock;tree stump; a person in a canoe, anything of interest that would be a main subject.
I would also like to see more of the sky, perhaps a virtical composition would have worked better.
Lastly, the tree branches in the foreground need to go.
It's a pretty scene, but needs a clearcut subject and more sky in my opinion.(take that with a grain of salt, because i'm not much of a landscaper
)
