Went to a lovely park one day and took a ton of photos. Standing by the edge of the pond and seeing the reflection of the tree plus the real leaves floating on the water inspired me.
Caught your image here before, bookmarked ... and here I be.
Suggestion: Add in the make/model of the camera you are using and what image editing software you have at your disposal. In your accompanying narrative.
Might provide a leaping off point for your viewers and commenters to add some further tips and suggestions.
Carrying on ...
Really like the feel and mood of your image here.
Caveats?
Some of the areas that are near 'white', could ... in my humble opinion, of course ... use a lil' editing assist in bringing out some more detail. A lil', nothing major.
Perhaps, it may come down to simply adjusting your in-camera setting(s), and in particular ... regarding Exposure Compensation (<--- bit more indepth, but the concept is presented well and succinctly). Common feature to most makes and models.
Good composition.
Really, really ... as Jan and Chris make mention of in their above words ... "clever" and "artistic". Well done from me.
Again, 'nice work' indeed applies. I see a lot of aforethought and a judicious choice and employment in adding in the toning.
And but of course, thank you for sharing this one with us. :o)
