This area could be improvement in various aspects, the screenshot speaks for itself.

Yeah, the midtexture at the very least needs to go all the way to top and bottom. Or replace it with one that can work not reaching the ground. Either way, change it.

I dunno, the midtexture gives a sort of feel of abstractness, which is what Hell is all about. If anything, the ends of the midtexture should be detached from the map geometry

Yeah but then a different midtexture should be used. This particular one is meant to connect and it just looks bad. There's a difference between abstract and bad.

This has been already fixed, hasn't it?

Sorta? It's better, but not perfect.

I was going to mess with it, but then I didn't.
