I have further developed the sewer level blockout
I finished the jumping area and put a ceiling on it.
I added a small brown patch beneath the tree to look like dirt.
I then added the final area of the level. It is a large platform that will have a set piece event.
With that, the level structure is complete. I will now add the little things around the level such as railings. These will only be loosely represented as it is a blockout.
