I'm such a dork. I think that Mos Espa shot must be from AOTC, because I don't remember any shot like that in TPM. That means it would be a CGI town too :( But if it's passable for the quick shot you're using it for, I guess we needn't be too picky.
As for shots from the back, there is the Falcon leaving Hoth base, traveling through hyperspace in ANH, and probably several other shots. I don't know if they are what you're looking for, but there're a couple ideas for you.
