The image on the left is a bit too abstract to "go with" the other 2 images. The shadows are a bit too dark as well.
The image in the middle has a bit of leaves obscuring the left arch. (What a pain to clone over bricks!)
I think the picture on the right could be improved by showing more of the fence to include all of the road. Your DOF in all 3 is impressive. Comments meant to be constructive, hope they help.
I'd like to see this a little sharper and possibly even with a touch more color saturation. The left two images are my favorites; nice theme with the leaves moving down the river and under the bridge. The third image doesn't really seem to fit (I had this happen with my entry, too).
