Thanks all.
John - I'm not entirely sure i pulled it off a few people i showed it to didn't get what it was meant to represent.
Ruth, the ID shot is great, a fabulously simple idea that probably helps hugely in making sure you have the right patient.
I don't know if it is the image compression that I get when I connect via my mobile but the image appears a little soft to me.
I think the softness your seeing is because i took the pic at iso 1600 to add some grain but it didn't really work and once compressed for web it looks a little off.
You confessed too quickly Ruth. My interpretation of your picture was that you have focused on the name band and deliberately made the arm slightly softer to emphasise the theme of Identity. I like the mono treatment, too.
Really good interpretation of the theme - and I haven't had time to do a reshoot as well, so I sympathise.
