Nice effort cade. Personally, I'm not a big fan of all this color 'correction' going on in this thread. In my opinion, TPM is the only movie that really needs one, because of the pink tint.

You are right that the change in colors changes the mood of the scene. In this case, it makes it more bleak which fits I guess, but I like the original sunset better. Lucas often uses sunsets in scenes like this, in this case to illustrate that the sun is setting on the good in Anakin. Kinda like the final scene in AOTC, where we see the sun setting on the Republic with the deployment of the Clones across the Galaxy.

The new music fits very well too, but once again, I prefer the original. I think it's a little creepier and sounds a little more sad, don't know of that makes sense :P. I admit that the original music doesn't sound very Star Warsy, but I hink the music you used sounded a little too much like Lord of the Rings.

But overall, nice effort. You definitely should do a ROTS edits. I think it's always nice to see a new vision on the prequels. Have fun with it!
