New
Old
Above to the left is the new graphics and to the right is the old graphics.
The difference I made was adding a darker variant to the background and a lighter variant to the foreground. By doing this, it distinguishes the the layers, giving it a type of 3D look, even though it is 2D.
The colours are a lot darker in the newer version, this is because I wanted a more dirty dungeon feeling and I think I have achieved this by doing so.
