I really like the model but the scale is a bit...big? This will dwarf any ship in the area not to mention cutting right out of manhattens atmosphere: to clarify, look at this picture below-
It would jut out reducing alot of space infront of manhatten.
I suggest scaling it down- no real remodling is required with the shipyard, just replace the trains with like one Transport.
Thumbs up on the model itsself though- great work:)
