Alright...enough nice comments..time to tear this one apart....constructively ; )

First off I must say that this is a nice image, but there are a few things that are bugging me.
The hoizon line cuts right through the middle of the image. It is not particularly bad with an image, like this, that has such a busy background, but it still jumps out at me. If you could have gotten up higher somehow or maybe lower looking up....this is just too straight on for me...

The bridge would have more impact for me if more of the path was visible...leading me into the park. I'm not sure how one would accomplish this and still get all the wonderful details in too. Probably just slight shifts in position and angle of view.

The bits of shrub and white flower/weeds in the foreground are the most distracting to me. My eye is always being led to the bright white flower-weed right up front and is keeping me from truly enjoying this image.

Top of the bridge seems a bit "hot" or washed out....due to difficult exposure though. Overall nice tonal range.

I like the fact that there are no distracting people in this image..makes it seem much more peaceful.

All in all an very nice image.

-Just one mans opinion-
