I just checked the Ben-new.mp4 to see the difference, did you make 2.1 slightly brighter? it's hard for me to tell but i do see some slight colour differences. Also is this scene now closer to the I.B print your working from, or closer to what some people wanted the scene to look like?
Edit: I just checked the screenshots and now see it looks better to me in 2.1, great work Harmy :)
