First off, I want to say I love this image. I think the composition is perfect, and inviting. it feels like a cool, start of spring morning. the hint of reflections on the water seem to pull me in toward the bridge in a subtle curve.

Since you asked for input, I have a few ideas.

The one actual "correction" I would make is the left to right exposure. I know in Lightroom you can use the Graduated ND filter, and get the exposure and contrast to match across the frame.

If this were my own work, I would boost the contrast. I would use maybe a +10 contrast (and brightness to keep the level of light), +15 to clarity (to add some detail to the bridge, grass in the foreground, and trees along the left side.), and maybe even increase the blacks a touch to maybe 5 or 10 max.

I think this would also make for a really amazing high contrast B&W, maybe even with red filter... I would have a lot of fun with my NIK Silver Efex plug-in for photoshop
