I don't think some minimal tweaking would ruin the "integrity". There's no denying its origins.
Since Badejo is not in that display, things don't even out, its simply an " as molded " situation, not necessarily a true reflection of what image we all responded to with such admiration. Which I would assume is not just pulled from the mold castings w the neutrality of the necessary pose for ease of casting.
Smaller changes are what I think most have suggested ( aside from correcting the head issues ) It could still be a full standing display.
Were it to be put into the crouched postion , perhaps some "integrity" would be lost, minimally I think, but it still starts w Giger sculpted castings.
I like Gigers museum copy too, but were I to want an "as molded" display, I think Id want the finishing work that Giger did for his copy, which is not screen accurate :love
Guess its just a personal preference. For me I wouldnt be feel any less enamoured w the beastie if he was reposed. :cool
