Hi Fox,
Your picture should would go well with oboe music... I love the oboe (my brother plays it quite beautifully) and I like looking at your picture. On the critique side: besides what Rob said, I have the feeling that the reds are a little intense and that a tripod could have helped to keep the motion-blur under control.
I am not sure whether it is considered bad style to offer a subject related shot of my own in such a thread, but I made the picture small and the moderators are certainly welcome to remove the picture. So, here is my take on the topic 'sluice'. To prove once more that I am a weird guy, I kept the water out of it...
Cheers,
Peter
