What wad is this screenshot from?

[Doom_user]

I found this screenshot saved in my Doom folder. I remember saving it, but I can't remember what it's from or where I found it.

The sky alone is very likely from Artica parts 1-3 for Boom and Mbf. Could also be the level, especially judging from the brick theme. You might PM Cyb (the author) about this.
