Love the picture. Really clever. I presume that with a 10 second shutter speed you were using a tripod. If so why did you have the ISO at 1000? I was always under the impression that when using a tripod you can have the ISO as low as possible this way you can avoid unwanted noise in the picture. I think i it may be a little too dark so i have uploaded a MOD for you. I messed around with the shadows and highlights and then tweaked the brightness and contrast using adjustment layers. I also sharpened the picture.

This has the potential to be a great picture. But sadly the top of the boat is missing. It really needs the top in my opinion to be a great picture. Also i would try and use a touch of vibrance in the picture to really bring out the colours in the picture.

Love it. Looks really good in black an white. I would be tempted to try and clone out the girls head at the bottom of the picture that is below the boys chin. As it is a little distracting. This way the focus would lie with the boy ant the front and them you would slowly work your way around the picture to the other children. I may be also tempted to crop out the girl furthest to the left as she seems out of focus.
But what a great picture!

I think that the picture needs to be cropped in just a little tighter to be more of a panoramic look. Also it seems just a little bit flat to. I have uploaded a MOD to see what you think. But a great capture, i am so wanting to take a picture like this.

I think this is a great picture but have you thought about cropping in really tight on the subject. Maybe in a square crop to get really close in on the subject. But a great picture overall.
