Well, in a nutshell, I didn’t like:

The jump cuts from Ben and Vader walking to them just standing there. This happens multiple times before they start dueling.
Some awkward editing when Ben says he will become more powerful than Vader could possibly imagine. It switches between original and SC38 way too much.

It’s only those areas that bother me, although they bother me a lot. Most of the issues I have are with the sound not matching up to the footage, which I guess is inevitable for an amateur sound mix.
