Screenshots look good. Not sure I can notice much with the tweaks other than it looks a little brighter in some parts - something like this will happen anyway with people's various screen setups - not sure if it's worth bothering with or not d_j. I am personally happy either way if I am totally honest though.

Also, the lightsabers look the best they have ever done when you compare other sources/versions.

The most interesting test will be how the lightsabers look at the end of ROTJ when luke and vader are fighting - vader's lightsaber always looked muted or pink in nearly all versions I have seen - was worse in 2004SE but still present in older versions.
