I love this picture. There's something very positive about it, happiness if you will, and it feels calm. Lots of wonderful exchange going on, with touch in the lower left, the bowed head of the man to the right, the old man looking back, the lady looking right at us from the other side of the barrier, white cowboy hats looking the other way, and black cowboy hat looking this way, I'm guessing at the guy in front of us. This is really wonderful.
Love that glow our subject has, as T said, positive energy emanates throughout this, a great moment to have been a part of and great that you memorized it and shared!
