To keep the continuity of the effects from the prequels to the OT and possibly beyond. Though no matter how hard you work on Ep IV you will never get it to look like it was made in the last 10 years. It was evident between empire and a new hope because way back then in 1978 they had no idea how to even film a light saber sequence or laser gun battle.

Ive seen a lot of other fan edits out there mine will be the most conservative that You might see. Outside of a few audio additions to IV and of coarse Han shoots first, my objective is to take a hand drawn laser effect and to replace it with a digital one. In my opinion it brings more suspension of disbelief then before.

If people are going to be critical to no end then I will never release it and I will just personally enjoy it for myself. I was just thinking other people would enjoy it at some level.
