Sorry about the "dude" Fran.

Well, I've managed to build something I quite like but I'm not happy with the rendering.  Before I spend 18 hours playing with it can I ask for any suggestions on what I've got wrong.  I'm not sure about the materials but I don't know what to do to them in order to get them better.  I'm fairly sure that the haze doesn't look quite right but again I'm not sure how to change it.  Some people get the most incredible photo realistic stuff out of Bryce and I'd love some tips on this one as to how to get closer to that.
