Photo Critique requested

Hello Everyone, I recently picked up a C5050z and got the two Canon lens's Wide Angle and Macro, and was wondering if you all might be able to provide some review and suggestions, I have posted a few photos at

http://www.crawford.winisp.net/working/

and I am using some Sony video lights until my strobes come it.

The pictures were taken in Seattle at a very common dive spot known as Alki (aks Seacrest Cove 3)

Thanks,

Travis
