OK, what I was planning for this map was a huge gothic/hellish castle floating in the middle of a sea of blood. If that doesn't fit in with what you're planning I could start another map for this project. Here are the screenshots:
I'm planning to use a stacked sector in that second shot to make it look 3D.
I just started a map using the gothic textures a couple of days ago. If you want, I could contribute it to this project. If you want to see what I have done so far, just tell me and I'll get some screenshots.
