My comments
1 - Its a lamp post, I think. If there was something that would draw my eyes to the branches, a silhouette of an owl maybe, that would be an interesting picture.
2 - Too many intersecting lines. My eyes keep going in and out of the frame. Background is also bare and flat. More dominant blue sky and some clouds are always the best combination when shooting with a sky background.
3 - Depth of field is a bit shallow. For shots like a group of small subjects, I prefer all of the seedlings to be clear and crisp.
4 - My eyes are drawn to the window, not the dog. It would be interesting if the OPEN sign had minimal glare and you could see through the window. You can minimize the glare if you have a CPL
5 - The mushrooms are all singing the same tune. If one of them were inverted or if you added an orange, you have a lead singer. That would be pretty.
6 - Nice motion blur effect. I like this one. Why? Pretty interpretation of lines and curves.
7 - Fog or is it smog? Anyway, it would be more interesting if the boom ran diagonal pointing to the upper left corner
Just like you, me, and the rest of us here, we were born with very good eyes. Can it be trained to become a photographer's eye? Yes. Constant practice makes us see beauty even on the most mundane thing. You dont have to go far. Maybe the subject of your prize winning photo is just sitting there in your backyard waiting for you to pick up your camera and take a shot.
