Hmm... regarding your light saber clips Omen for me their very subtle differences to make a strong choice either way but if I had to choose it'll be:
lightsaber3a - because the saber seems to be fuller & it might be me but I slightly see a kind of stronger glare when lukes swinging it that adds to the scene.
Also regarding that scene I wonder why in all of georges tinkering he didn't add a light saber reflection to C3PO in that scene over the sabre props stick shadow ?!
lightsabercantina1a - Now this is why my 2 pence worth can't count on this whole lighting thing because of this darker cantina scene the saber seems to not benefit from regrading as it seems to me to be too vivid for the whole dark canteena scene as a whole.
Sorry Omen best leave it to your judgement on this or someone with a stronger view either way :S
MERRY X-MAS ALL
