I would love some feedback before I officially submit it
It's OK, but there are several really good door SCPs that it's up against. SCP-004, SCP-1691, SCP-249 and SCP-384 are all doors, and 004 is one of the higher rated items on the site. If you're doing a door, these are your benchmark.
In addition, this is a door that makes you go mad, and things that make you go mad are somewhat of a sore subject around here, getting it sandboxed was a very good move, I would keep this evolving for now.
Tone is atrocious, there's almost no professionalism to it, and it literally looks like the person writing it was holding back snickers the entire time.
If it's localized to a site, and the Foundation owns the site, then it's contained. It's just not the type of thing that folks at said site like to deal with. That said, EVERYONE AT THE SITE should be instructed "Hey, we've got this thing here that makes you see doors where there aren't any. If a door doesn't look like it belongs there, or if you're having issues getting through one, it's this."
The "uproar of comedic incidents" would probably result in a site-wide meeting with the local Site Administrator dress-down everyone in attendance and reminding them that they should know damn well what's going on. And that it's safe, and that nobody should be requesting Euclid status unless things start jumping out of the doors and biting peoples' faces.
(Please don't make things jump out of the doors and bite peoples' faces. We already have several of them)
Finally, the last couple of notes are what we've dubbed "lolfoundation". It would show up in someone's private in-box but has no business being attached to a formal report.
Okay, I re-wrote most of the article, And attempted to keep the sterile, Science-ey report style
I still don't think it's up to the level where you should post it, I'm afraid. It's very basic, and you're overusing black boxes all over the place. In terms of the SCP itself, it's not strong enough yet, there's no hook to make it stand out. A door SCP is a hard one to do well.
