Tree billboards

In gaming graphics, a billboard is a type of 2D image that always faces the camera. I found some high-quality free images of trees at CGBookcase.com, and created several billboards of trees to fill in the edge of the world map. They are only visible looking out of the 3rd floor windows of the school, so it is hardly noticeable that they are rendered at a low resolution, or are rotating to face the camera. There is also enough variety that, from a distance, it is not apparent that there are only 4 types of trees. 

Oh Hi, 2D sprites!

I also used a set of textures (https://cgbookcase.com/textures/polished-concrete-01) from the same website to replace the basement floor material. It now looks more like how it should.
