Oops! Good catch - the turtle pic shouldn't have been included (wasn't shot with the strobe).Very nice! A little work on composition maybe, try to put some angle into the straight down shots when possible, and or use the lighting angle to create depth. Other wise, the clown the frog and the turtle are all very nice. Not sure what the guide number is on the mini flash but the turtle shot was probably pushing it's limits for range.
Composition is challenging for me, especially with even mild current and/or keeping up with a dive buddy without a camera.
I appreciate the feedback from everyone - thanks!
