I didn’t read every other post so sorry if this has been discussed already but imo this scene is “busy” because the lines are all over the place. The branches are going several different ways, the water another, and there are no real leading lines to the subject. This is just not that easy to look at. Now, that is not a knock on the technical aspects of the photo as capturing the right exposure with this type of scene is difficult and I agree with not blurring the water but... Compositionally, I think a different angle with maybe a wider perspective that somehow leads the eye to the subject by using those branches would improve this. I viewed the rest of the set on Flickr and don’t see any other takes in this scene so maybe that was the only angle? If so, maybe some dodge and burn to darken the background and better isolate the subject would eliminate some of the “busy” aspects of this.
