Overall a nice image. It has a subject and good composition. I think it could be slightly better. The trees and little building don't add a lot to the story. The subject, to me, is canoes on a pond of duckweed. I would isolate them and clean up the pond of all the distracting elements. I ran the tonal contrast filter from Nik on it as well (I like the look, but it looks good with out it also. I added, you guessed it, a vignette.
