Ed,
I'm really a fan of Jo Sonja Iridescent colours, but I think you've made two mistakes.
I think you've used your fingers to create the sworlled effect, the lines Les refers to are (I think) your fingerprints, a large artists brush would have been far better.
The second (again I think) is you've mixed the green with the gold. I've yet to see the gold actually look good, it's the weakest of the colours and has drawn the green down far to pale.
Having said that, I think the design with the beads delineating the coloured areas is effective.
