Well, as I wrote a number of days ago. Maybe even a week and a half, I was having serious, serious problems with this image. Now it's fine. I posted my problem on 3d Buzz, an awesome site full of people who cater with fearfully accurate advice.
Their advice helped. Just take a look.
I've changed the angle, the colours, the amount of reflectivity, the depth of field and done some small modelling touch ups to create a closer inidication of the final form of this image.
