Very Nice Bess. You really have grown as a photographer.
The Hidden Treasure photo is intriguing but my eyes want the background buildings to be a little more lit up. It has a feel of too much negative space on that half of the photo that can be drastically improved by bringing forward what already exists there.
The fireworks series is impeccable. Outstanding. As are the pictures from the boat. In Exhaustion I feel it is too tight of a shot. Cutting the hands off in a weird location appears unnatural. Maybe go for the cut on the wrists. I'm also yearning for a little more head with hair strands coming to the top of the forehead. Help define his body. Maybe a smaller aperature to bring his entire body into focus to cause him to "pop" into the frame.
But who knows, I could be wrong. Art is in the eye of the beholder
