Sewer Hallway

This sewer hallway took about 3 hours to model in Blender for the 3D Art Jam. I used the array modifier to make multiple duplicates of the model so it will look more like a level in a game. I UV unwrapped so I can texture paint using the color grid. There are scratches on the pipes and mud on the edges of the concrete floor going towards the middle were the dirt and water is. I tried to make it look like the water in the sewer had bubbles.
