Nailed the composition, however the tones are a bit lacking and the water is a bit distracting. I think one think that could add a lot would have been to do a long exposure to smooth the water, also maybe brightening up the heron, or completely making him a silhouette, right now you can still see just a little bit of detail in him. It needs to be one or the other, nice job with the shot though.
Nicely framed. Would have preferred this in colour as colour images similar to this have historically scored well. Nonetheless a well captured image. Good Luck. 6.
