In regards to the Europacrafts "Birds" set, that particular mould-kit is not an exact match; although, it's very close. There were two vintage Supercraft Ltd. sets that are believed to make-up a match (however disputed), but are no longer available (also guessed to had been used for the film). And nor are the original studio moulds anywhere to be found.
Maybe Europacrafts' is the best one can get without a lot of eyeballing the scene, and hand-crafting them yourself (based on your own visual interpretation), as in Rick's specialized case. I understand he has carved-out custom bird sets for a few others, before. Anyway, all I was able to find-out for the time-spent (from various sites).
Portrait of a Replicant by Alex Ledante
According to Alex, a portrait based on a scene I certainly don't recall (possibly deleted, too): 
(Excerpt)The full title of this piece is "Portrait of a Replicant and Other Dolls" because I filled the background with things that relate to the condition of these fine Nexxus products. One of the best parts in Blade Runner was Pris attempting to hide the physical evidence of her accelerated decrepitude with make up: Trying to pass as human by, ironically enough, looking like a doll.
You're welcome, Dale (+thanks).
Sawa;)
