Blender Subways Flood Simulation

I recently Started working with the Blender 3D program. It is a wonderful program but a little hard to get used to...

I made a model of an entrance to a subways and created a flood simulation.

Its pretty low quality but thats becuase it takes about 2 hours to render a 10 second clip...

I really want to do a more detailed version of this so I would like feed back to see if the water looks even sort of real.
