first photos with S2 pro in Ike housing

This is from my first ever set of photos underwater. So any constructive comments would be appreciated.

They were taken whilst on a small Island in the Tarutao national marine park Thailand.

I shall set up a website at some point to show the better ones

Can you post the information about the shot? It looks like you had a very smal DOF. I always use f 22 or higher while shooting macro. This gives you the maximum DOF but sometimes is still not enough for some subjects.
