The second one below the dot, please. I'm a bit of a noob and would love some advice as this is my first keter!
Here we go, comments made as I read.
- Not to be overly macabre, but what if someone does not have legs? Would they develop skin decay anywhere else?
- Only refer to an individual as a subject if they're actually a subject of a research experiment. Otherwise, they're not subjected to anything, and also it might make it seem like the anomaly only manifests in controlled experiment scenarios.
- the list of "door-to-door recruiting, mail leaflets (see transcript of XXXX-1 distributed flyer), social events and group therapy programs" is a liiiiiiittle clunky in that "mail leaflets" aren't really something that someone gets involved with the same way they do recruiting or programs. Smoother parallel structure would be "distribution of mail leaflets" or the like.
- Are all the flyers distributed by the SCP-XXXX-1 instances the same? If so, that should be noted. If not, maybe provide multiple examples of such flyers?
- "it will attempt to retreat to a small hole within one hundred miles of the area, or to create one if one is not readily available. " --> vague. What defines a "small" hole? What qualifies as a hole for these purposes?
- " instances of SCP-XXXX-1 enter the final stage of transformation into a full instance of SCP-XXXX-1" is kind of confusing. How is a full instance of SCP-XXXX-1 not an instance of SCP-XXXX-1? How can someone tell the difference? Why not create an XXXX-2 subdesignation for the individuals who reach the "full" stage?
- It looks like you've got a collapsible within a collapsible, and as such the second collapsible opening code is broken.
- miles are not metric.
Overall… this is pretty ambitious, and while I have a few misgivings about the wording in a few places, I think I like where this is going.
Fix up the grammar/syntax stuff I mentioned, maybe read the piece out loud to check for any other awkward phrases, and I think you're good to go.
