The cruise ship sailing towards Canterlot

This is a artwork for a up coming fan fiction I'm working on about a human cruise ship  being taken over by a creature referred to as the Anomaly of the Seas. What happens is the the Anomaly makes the cruise ship slide though a worm hole in the Bermuda Triangle that takes it into the Pony's Dimension. Once it is there the ship is forced to sail though a giant system of rivers referred to by the Ponies as the Great River. The Great River leads the ship though several sets of giant lock gates and even a giant 30 mile long tunnel under the Canterlot Mountains in till it gets to Manehattan.

What is going on here is everyone is waking up on the ship after blacking out after it slid though the worm hole. When the ship slid though the worm hole at 3.00AM in the morning everyone blacked out but was not harmed by it. Leaving the ship to operate under her own power though hurricane that keeps people out of Equestria referred as the Sea of Storms. The ship though makes it though the Sea of Storms do to it's shear size and power making it into the Great River system.

The ship's new navigation computers meanwhile as the people wake up on board keep the ship from slamming into the walls of the Great River. In that the River here might look really shallow on the surface but in real life the Great River is some type of deep geologic fissure that opened up in the land linking Lake Manehattan to the open ocean. The bottom line though is that the river the ship is in is many hundreds of meters deep even though iit's almost land locked.
