That's good to hear. Do you think the ghost would be better to show immediately behind the pyre or off to the side? I imagine it could be shown in a close up/fade-in (like the '04 version and later, only with Shaw's head). When we see the distant shot just before panning up, it seems that we could fairly easily use Obi-Wan's body to make the shot complete without looking fake from the distance. But again, you're doing the effects, so I don't really know how easy that is.
Let me add that I'm so glad we have you on our team. You are an invaluable asset. Thanks for sharing your talent.
