vaderios, while I'm on the subject of the Wampa(s?) for a moment, I'd also really like to see you take a shot at making the head on the 2nd appearance of the Wampa look more like the one from it's 1st appearance in the top shot here, sometime. (No wonder they kept it's 'lunge' so brief, and had it's paws up in front of it's face, obscuring it a little, lol....)
Here's a couple of good angles of the 1st appearance prop. As well as the obvious differences on the faces, I preferred the 'lop-sided' look to it's ears in it's 1st appearance, compared to the 'pointy' ones in it's 2nd one. (However, I do prefer the 'gnarly' horns seen on the new SE suit, and would like to see more of a hint of these (or even just 1!) added to the 1st appearance shot too!) -

That was thoughtful of you to contact the 501st guys about a Vader suit for the 'hologram' by the way, and neat that they got back to you about something of use too. I'm curious to see the one that Adywan made for himself that may be used in that shot though.
Anyway, I'll leave you with my favourite piece of artwork of a 'lunging' Wampa -
