A couple of things I'd like to see in this shot
a) Color. I think you would have had a nice sky to work with. The sepia makes everyone blend into the background
b) Everyone looking at the camera. Kinda nitpicky though. Trying to get this many people on that sort of apparatus all looking in the same direction at the same time might be tough.
OK, this is a really fun shot, well directed and executed BUT using sepia has not added to this shot in anyway. Sepia is usually used to add a timeless quality to a shot, here I would of opted for loud garish colours to enhance the fun factor.. Still, as a large print this would be great for any member of that family so dont be downhearted by the 6 I give here, to the family here it is probably worth a million at least... well done..
Fun group portrait. You might have taken an even lower(or closer) camera position to get rid of the distubring background. And to be honest, I think sepia sucks in general and it sucks even more in this pic, as it is totaly misplaced in the fairly modern context of the picture. (5)
i love the different idea of everyone being on the net but not sure i like the sepia effect..i think it would have more appeal to me if it was in colour.. but that is only my humble opinion, otherwise it is great.
