In it's very first appearance near the start of the movie, it has a 'yellowish nose and eye areas', with inset black eyes, along with just a hint of it's horns showing, which are largely covered in fur, and with a hint of one ear tip set to the side of it's head. But in the 'lair' sequence of the 'special edition', both the new 'man in a suit' face and the original 'man in a suit' face have NO 'yellowish nose and eye areas', but have faces that are completely 'furry'. Their horns are fully on show now, with the NEW 'suit' design having dark, gnarly horns, set closely agiainst it's fur, while the ORIGINAL 'rushing toward us', Wampa 'suit' design has a lighter, smoother, more semi-circular horn, with a gap between it and the fur. On top of this, the original 'suit' has a more pointed head, and very prominent, pointed ears on the top of it's head, compared to the new 'suit'...
My own favourite Wampa design is the the one with the 'yellowish nose and eye areas' on it's first appearance, although I would like to see the more noticeable horns added to it. I would love an enhancement of the later 'suit' faces to resemble this appearance, but accept that you may prefer to actually make this first appearance more 'furry' to tie-in with the later shots!...or may even just leave the two differing 'looks' alone and separate as they stand! I note that someone previously suggested that this 'lair' Wampa could be a DIFFERENT Wampa to the one seen at the movie's start, and that there might be two of them in the 'lair'... I don't know if I really like that idea, but it could work okay I suppose if there was a hint of another one, RATHER than just a 'second roar'.
Anyway, here's my own suggestions for the actual re-edit of the 'lair' sequence, which would restore it to something of it's original 'pacing' -
I'd get rid of the first THREE shots of the over-revealing, over-lingering, NEW 'suit' altogether, and re-instate the ORIGINAL brief, mainly hidden 'walking' shot with 'growl', while keeping the improved shot of Luke freeing himself and falling to the ground, which now features the close-up of the Wampa's paw and side. After the shot of the cut arm falling to the ground, I'd then keep the shot of the NEW 'armless' Wampa roaring in pain as the final reveal of the beast...
However, if as someone previously suggested, that you just get rid of the first TWO shots of the NEW 'suit', but use the THIRD shot of the Wampa 'standing up', in place of the original 'walking' shot, then I dearly hope you will SHORTEN it a little, cutting it short just after the 'little bit of meat' falls, BEFORE it starts to walk towards us, as I think it lasted far too long. Finally, if you DO use one of the first two NEW 'man in a suit' shots at the start of your 'lair' sequence, then I hope you will just use the SECOND one, the 'close-up' one of it eating, and NOT the first 'hunchbacked', lingering one... This would of course explain the 'blood' on the fur of the final 'armless' reveal, or you might even choose to remove the 'blood' on the final 'armless' shot if you choose to use the ORIGINAL 'walking' shot. Alternatively, you may choose to ADD 'blood' to the fur of the dismembered right paw on the ground, as well as to the 'mouth/chin' area of the ORIGINAL 'rushing towards us' Wampa 'suit' to better match everything else...
Good luck, and I will look forward to your eventual choices whatever you decide.
