Always amazes me to see birds flying in tandem. Especially ducks. they make me think of two fighter jets flying wingtip-to-wingtip, in perfect harmony, each supporting the other.
interesting how you've built that perfect synchronization and contrasted it with the silhouette lone person, standing under a leafless tree, in the fog.
I like the composition, the character seems to be linked to the tree and the birds are very well placed.
Nice gradation of tones from bottom to top.
