This is a great photo. I love the dynamic sky in the reflection. I also like you horizon placement. You will probably take a hit and get some comments from the small size so I recommend you look in the tutorials at "Using Photoshop to Prepare Photos for DPC Challenges" by EddyG regarding resizing. If you do resize it, post it in your portfolio so I can take a close look.
Nice. There are just so many water shots that in order to "Creatively photograph a reflecting surface that is not a mirror" and stand above the rest there has to be some grabber. I will be back to re-evaluate after I look through the rest of the shots. (In future challenges I think you would be better served to submit larger images also.)
I love this photo. The colors, and the leading lines of the river banks are beautiful. However, points are nocked off for the small size. There is a tutorial on how to make your picture larger and under 150k. good luck in the future!
