I would love it if you guys could give me some constructive criticism. Ive been taking UW pics for about two years and am a keen amateur/novice, and would love to hear some advice to get my brain thinking about improvement. Heres three semi random shots:

This was taking snorkelling in the Galapaos, with an Olympus Stylus 700 point and shoot with an Inon WA fish eye lens 165.

This was taken in Tobago, with the same point and shoot except with an inon macro lens, sea and sea ys-27 strobe, and a focus light.

Taken in Galapagos, with the same set up as the second shot.
