I think since there's not a thread on it already, you're probably in the clear.
One of my favorite things about this level are the backgrounds... there's some very good screens in there that show the "proper" way to use some of the standard tilesets. They're textbook examples of how to make areas feel vivid and open and alive and 3D... not flat like some screens. It's amazing how many perspectives AlmightyZenTaco manages to get in some of these screens.
