Keep current. For the record, proposals to remove an image from a nightmare fuel page can go in the Moments Images Cleanup Thread.
I had specifically asked in the IP discussion thread if that could go in there, given my main concern was that it was added without discussion and the moments thread didn't specify if those qualified to be posted. Nobody answered, so I waited for an open slot to make this thread in the event a "changed without discussion" case required starting a thread.
I found this screenshot from the same episode; would this work better than current? It's a monstrous creature trying to attack Stevonnie as night is falling.

Hmm... I kinda like the current, very House of Broken Mirrors, plus the fist.
This shouldn't be a spoiler, but please correct me if it's problematic. "Rose" shattering Pink Diamond in "A single pale rose". I think the top panel might be enough but included 2 just in case.

Out-of-context, that looks more Awesome than Nightmare Fuel.

The page source shows "Image removed per Image Pickin' thread", which links to this thread
. Just a few edits after the previous image had been removed, a user named dknights411 added a new one unilateraly
- and that one was never brought up in the aforementioned thread.
It currently has this:
I suggest pulling it regardless of replacement, because I fail to see what makes this image scary. The worst I can see is an angry face, but that alone nightmare fuel doesn't make (not to mention it's broken up and surrounded by bright colors).
