Eye See You...

Today was play day. With work looming tonight I was running out of time. I have seen numerous eye shots and always wanted to give it a go. However mine didnt work as Id hoped. I have a macro lens 105mm which I have seen others use but no matter how hard I tried I could not get the iris in focus.
Admittedly I was trying to take a picture of my own eye by using a mirror and live view but got so frustrated in the end I gave up. This is the result.
Im not happy with it but I have to put something on Blip today.
All helpful comments appreciated.
