Very cool shot. I look forwad to the days when my son will be old enough to go hiking with me, and hopefully enjoy photography as well.
About the shot. I like the fact that you have a lot of the rocks in the picture. It gives the feeling that they are on top of the world looking out. Nice job.
I like this one. The desaturated sky really helps to make the subject stand out. The detail in the rocks also add strong interest. Good tonal range through out.
This is a VERY cool capture. Not being able to see what they're seeing really makes this shot work. It's like they're on the edge of another world, hidden from us. Well done.
