Cool edit, but I don't think it's for me. I've always seen Tarkin as the "main villain" in ANH, reluctantly accepting Vader as the thug the Emperor shouldered him with during his command of the Death Star.
This might just be due to the fact that I'm a big Peter Cushing fan; IDK.
Anyway, I don't mean to crap on your edit. It's an excellent idea and I'm sure it will have many, many fans. I guess I'm just interested in seeing if there are any other Tarkin fans around here...
