good stuff... gotta love maxwell, i played around with a bit a while back and thought it was the greatest thing since sliced bread! and the multi light feature is amazing, being able to alter the lighting post-render!
I used spherical objects with 24 sides (the less amount of sides the quicker the render in Maxwell) I applied maxwell emitters to them with an efficiency of 18 plus the default 10000 intensity ratings. I also used a skydome with a level of 4 and white.
The textures have bump, specualar and diffuse maps applied.
