Hi. Just watched some of the preview. So, thanks to begin with. I understand this is a preview, so I suppose my concerns will be corrected in the final rendering. Here are my concerns:

- After the opening crowl, blacks are not that black. They're grey. In space, on Vader, in (not so) dark corridors where Leia and C-3PO are hiding, etc.

- The way it's cropped shows dark grey borders on many occasions, that are distracting. Very noticeable during the sweeps/fade ins, I don't know how to call them. And some are coming and going and reveal round corners. Also, especially on Tatooine, a yellow line appears in many cuts, on the one frame before and the one frame after the cut, that's also distracting. I hope you'll crop the whole movie differently when the time comes to hide that stuff.
