Hi Becki! Cute shot, and well composed. Do you know if the flash fired in this shot? It doesn't look like it, and this is one of those scenes that usually will not activate the auto flash, so you have to turn it on yourself. That will fill in the shadows of the boys' faces (hence "fill flash") and even out the exposure of the picture.
Alternately, as Major said, you could hold a reflector of some sort just out of the frame in front of them which would bounce a lot of light back into their faces and accomplish the same thing. Sounds like a pain, but it's easy when you get used to it. I have a reflective tarp that I hike with which serves double duty as a picnic blanket and reflector . . . and I wonder why the pack is always so heavy?
