Shots look good but too dark IMO. - My concern being that it may be hard on the eyes watching the film graded in that way for 2+ hours.
Oh and here's something i noticed a while a go, wondering if anyone else has - one of the large light logos you can see in the scenes where obiwan lands is that of Skywalker Sound. you can see it in one of the shots vaderios posted - although it is mirrored.
I'd be interested to see what you manage to come up with Octorox.
