1024 by 1024 is ok too, but maybe you want to consider to use instead of these 4 maps
one single map with 2048 by 2048, but this is up to you!
If possible, make the windows on the side wall of the station a bit bigger, so they will become
a bit sharper. ( with bigger i mean increasing the mapping of these sidewalls)
These are just suggestions, you don't have to follow them

I'm really looking forward to see the final station
