Thanks guys. The light top right was not diffused as we were experimenting with more dramatic lighting. So the shadows are quite deliberate, although it's a matter of taste as to whether it works or not.
The Q fish-eye lens is a fixed f/5.6 so no chance of stoipping down, but the format is so small that the DOF is immense anyway. No tripod, this was placed on a shelf and the delayed action used to prevent shake.
