This is a very strange map, but strange in a good way. It really felt like late E2 map. It's not perfect tho' - for example right from the start it could use some texture aligning.
I like this. It's certainly chaotic, but not really in a way that detracts from the experience. It really looks like Hell did a number on this place, and it's nice n' sprawling in a good fashion.
There's certainly some odd architecture in spots, but I'm not convinced it's not something Petersen would try eventually, given his streak of odd random details in maps like E2M6. I'd vote it in.
Although I love iori's Logic Core map, this one is a little weird. A lot of parts look pretty cool and imaginitive but in its entirety it's a little too abstract. It's difficult to make sense of E2's texturing but The Shores of Hell could definitely use a more defined style even though the actual E2 was a little bit of a mess, especially in the later maps.
