Lost Boy: The Art Room - Alpha Map Texture Tests

I have been playing around with Alpha textures to look of the concept art for the art room, I ran into a lot of problems trying to get the Alpha Channels to work, I eventually realised that I had to reverse the alpha channels - usually with an alpha channel the white is the part that shows up and the black is the transparent part but with my case it was in reverse.
