Another very nice piece of work there vaderios! I've been looking forward to Adywan's improved background to this shot to really open the scope of it.

Your version brings up something - I see you've added a couple of extra 'Transports', but I always thought the one in the shot was meant to be the last one to leave....

The other Transports that were evacuating Hoth would have been leaving throughout the AT-AT ground battle scenes which have gone on for a while now by this stage of the movie, and C3PO says "Your Highness, we must take this last transport...it's our only hope'' a few scenes before this shot.

On the other hand, Leia then agrees with Han to leave, saying "Give the evacuation code signal....and get to your transports" to the operators still in the control room with her.

On top of this, when Han and Leia's exit is blocked by a tunnel collapse as they try to leave, Han radios "Transport, this is Solo....better take off, I can't get her to you. l'll get her out on the Falcon". This seems that he's referring to just a single one that's left....although he could just be in contact with a particular one that he'd organised to get her onto, and although there may be others left, they're all in the same spot he knows he can't get to now....

So things seem a bit inconclusive. Perhaps either the "last" in C3PO's line could be removed, or the 's' in Leia's "Transports" could be instead, to clarify whether there's only one left or not at this point?
