I wish I had more useful comments to say than "wow"... But I think I'll just stick with a big wow to you guys! :) Everything I see here is spot on, also, that's some of the best usage of floaters I have seen a round, I hope people actually stop and stare at this renders for a while and study them and how floaters should be…
