Image 1: like the color best of the three. Too slow of shutter speed that the bubbles on the left don’t look attractive. Strange that his arms are by his side; looks like a sinking statue.
Image 2: love how the boy on the right is doing something different than the two on the left. Repetition interrupted. Sharp and face not interrupted by bubbles, though there are some coming from his mouth.
Images 3: Nice and sharp, colors seem strange to me. Muted in the background, but hair is like green. Never shot underwaterbefore; is it because of the direction of the sun above the water?
