I would possibly use a gradient in the lower right corner to reduce the brightness there.
I would also like to see a bit more definition in the cloud, since it is a b&w conversion you may get away with over-the-top highlight recovery.
I would like to see some more separation of the trees from the background at the base if possible, because that is where the restingpoint is imo.
Further more it would be useful if there was actually something happening in the image. A large bird in the tree, or near the waterfront. A worn boat perhaps, or something other entirely.
It is presumably meant as an atmospheric image, but I currently don't quite catch what atmosphere?
