your shot of threepio on the tantive doesn't look quite right to me. yes threepio is golden, but at the expense of yellow tinting the tantive white walls behind him.
you've obviously colour corrected but to my eye it looks like a little too much in that direction.
when I did the tantive.
I used the white balance filter in Vdub set to 235 235 235 custom value and exported the tantive sequence scene cut by scene cut.
I then used colour correction in vegas.
