Thank you for all your comments, suggestions and encouragement 
Composition has always been a difficulty for me and doesn't seem to come naturally.. I think I was trying to hard just to get everything else right and not thinking enough of how it was positioned. I think my buoyancy and confidence has improved a lot now, so I can start thinking more about this and start using those rules from those articles you have given me. I will look into those books too as most of the reading I have done is online. I may just have to get some reading for those long hall journeys. Perhaps I should ask santa..
I have now discovered the manual WB setting on my camera (better late than never) and I'm looking forward to putting it to good use next time I'm diving. I think the magic filter looks like a very good idea too, not sure I'm ready to lug around a strobe yet, but it is on the shopping list.
I was lucky with the turtle and got 3 visits over 3 days. There were 2 on the local house reef (Ras Ghamila) where I was staying and is on the sinai coast rather than Tiran Is, but Tiran is only a short rib boat ride away. I'd definitely recommend the reef if you want an easy dive up that way, plenty of rays, turtles, napoleon fish, barracuda, morays and more. I probably saw more there than from all the boat dives I did from naama bay.
I am going along to the local dive club on thursday as they have a guest speaker in on photography which should be interesting.
Anyway I think I am addicted, that or mad to book up to do open water to master scuba in the UK (stoney cove, brrr). So you will be seeing some more hopefully improved shots soon.
But until then, just a last couple I have just uploaded and then I'll stop boring you for now
