Hey everyone - thanks for all of the great feedback.

yeah, i've actually been to Tunisia and could have taken a trip out to where they filmed star wars, but I think we ended up sitting on the beach instead.

I haven't done too much over the last few days - I imported the last few details, such as the tree roots and the hot tub (which you can't really see, but is important nonetheless ) and I also sorted out the shadows and added a few backlights.

The atmospheric fog is still giving me a headache, but I seem to have it working a bit better. I have also increased the glow on the forcefield, though I am still not sure about that.

Here are a few screen shots.
