I just want to improve this sewer to its best!
Any feedback would be great
add some kind of tunnel(hole in the wall ) that leads to somewhere like an under ground traintrack … you can make the place a little bright and more larger so people can atleast see wats inside
Try to use sample images/videos of sewers from Movies, Films, Google Images, etc… and try to replicate some features they may have and look good for you and also probably listen to FatalError404 his advice was pretty good!
