SCP Foundation

This is for my SCP in progress. Do I need to add more? Please let me know. Any feedback is appreciated.

I'm not an expert on critiquing, but here's what I got:

First, you have to bold your Item #, Object Class, Special Containment Procedures, and Description headings. If you don't know how, do it like this: add two *s before and after your phrase, so that SAMPLE TEXT + ** ** = SAMPLE TEXT

Its a rule here that we gotta use metric units, not customary Heck, there's even a -J page on it!

incase needed

should (probably) be

in case it is needed

You should refer to the door's entities as SCP-XXXX-1

place in time. Sometimes opening to otherworldly beings.

Add a comma after "time"

This paragraph is clunky and sort of confusing. First; grammar and tone.
The paragraph should sound like this:

sometimes opening to seemingly extradimensional entities. Witnesses report opening SCP-XXXX to see a humanoid figure in black clothing wearing a 'Tragedy' opera mask. When the entity was asked "What are you?" or any similar question, it responded with saying: "You are not invited to the party." following this, SCP-XXXX closed itself, pushing the class D and senior researcherany witnesses outside of itself.

Next, you said "beings", which must mean that there are more than Mr. Mask Man. Maybe you could add a log of all the entities that emerged to spice the article up a bit?

Above all: This article is very, well, used. There are plenty of openings-up-to-other-dimensions Scips out there. Unless you add something to make this stand out from the rest of the crowd, this will be swiftly downvoted.

I probably didn't reach all of the problems, so just take this article with a grain of salt and wait for more reliable critiques. Wish you luck!

I've revised the post and am working on ideas for other beings that exit. I hope the fact other forms of sentient life can exit and possibly do considerable damage to the facility adds a spin to it. Any comments or suggestions help.
