I got a lot done today. Along with implementing glBSP, I added in animated textures, the sky, music(only for Doom 1 now) and fixed a ton of texture alignment issues. The biggest thing of all though was PWADs. While the first version of Doom.Net supported custom levels, it was horribly unstable and downright shitty. This time around I built the resource manager so that the number of WADs didn't matter and so implementing it was no problem at all, plus it works just like the normal Doom PWAD loader.
And now for what people actually come here for, screen shots.
(Sorry about the crappy jpegs)
