in fact the shot could be considered "in favor" of the sloped undercity, thus partially solving the problem ;)

Something like that:

Forgive the crudety of this, I mockuped a mockup from Vaderios, so it's all Vaderios' fault :p

Well, it would definitely make more sense as to how Luke fell onto the antenna, as opposed to just falling away from the city. If the bottom of CC was completely flat (or at least the part Luke fell out of), and the antenna was off to the side, why DIDN'T Luke just... fall to his death?

Yeah, yeah, yeah... I know... Jedi lifting powers (not to get sidetracked, but if Jedis could lift X-wings, much less rocks, wouldn't they be able to lift "themselves" and fly around like superman?)

Of course, you'd have to wonder who made the poor design of putting an antenna for things to get caught on right below a disposal hatch... You would think that when Luke falls onto the antenna, there would already be some clothes and junk hanging off that thing from previous door openings...

I'm imagining a ROBOT CHICKEN skit: a Cloud City resident decides to commit suicide and jumps down the shaft, only to get sucked out the door and gets hooked onto the vane. Then he sees the Millenium Falcon approaching the city... the whole thing could be him trying to get back in and failing horribly, only to hear the door beginning to open, out comes Luke, who lands on top of him and... what do you know! THAT is what is falling away from Luke!
