I really like the feel of this photo and the contrast between the barn and the outside. I would prefer for the end of the walkway to be closer to the left edge to allow for a greater view of the outside as well as to mirror the placement of the barn. As it is it is a little too dominated by the black. Nice job.
This is a pretty scene. I don't know about all the negative space. It seems a lot of space was given up and the only payoff is seeing the small opening of the bridge. I'm more than likely wrong about this, but that's how I feel. Personally, I would have liked to see the building framed between one set of uprights.
I cringe at the thought of trying to take a shot like this with my simple point and shoot. I also sympathize for all the 'it's too dark' comments that you'll probably get. I love this shot. It's a touch too soft for my taste, but you get bonus points for seeing this and thinking if you can pull it off. it's an awesome attempt. Kudos on a near miss.

This is a very pretty shot. I just wish there was a tab bit more light in the walkway to bring out a little more detail in the wood. But overall, a nice composition.
