Class 58 - Subway Walls

Today I finished up my work with the Subway wall tile. I still plan on adding water stains to the image, but I will do this by creating a separate image meant to be placed over the wall like a tile sheet or trace paper. Doing that will allow us to have variation in level design. It will make re-using walls more practical, it should save on time and not look too repetitive in game.
I started by changing up the pattern of the old wall so it fits better together, so this is the image pasted 3 times in a row. Tiles are a hard thing to create because the goal of a tile is to not be, well a "tile", it has to have a certain flow. And I personally think I managed to achieve that with this wall.  
I then started to change the visuals of the wall once I found a suitable brick pattern. The first image was too white for a scary underground subway full of danger, so I changed some of the bottom tiles giving them a brown fade going up, I did this manually which isn't something I normally do. I also added a small pattern in the middle of the wall giving it more character.

But I then decided to change it further by altering the hue and saturation of the image. and we are left with this image.
