That look on the baby's face is priceless... I've seen it on dozens of human babies as they gauge the distance from Mom to where they want to go and wonder if they will get there! Love the angle of the mother's head as well. Good focus on the apes---perhaps a little more distance set to put the ground in a bit tighter. Great subject. Maybe a touch dark, but probably more on my monitor than anyone else's.
