Ok, so I will be frank, your description is currently very incoherent and difficult to parse. But I'll do my best to understand what you're trying to say.
So, first of all I don't think SCP-2996 is considered a commonly known SCP, so to base the majority of your article on a crosslink will not be a great idea. Generally SCP articles are expected to stand on their own without knowledge of other articles.
Secondly, I'm unsure what the actual anomaly is here. Like, you mention a floor trap, but I don't understand what's anomalous about it. And if I can't tell what's anomalous, I can't figure out what sort of story you're trying to tell.
Thirdly, is english your first language? I ask because if it's not it might be easier to contribute to one of our many branch-sites where you can use your native tongue. Writing an SCP is an uphill battle for native english-speakers, it's only going to be harder if you try to write one in a language that is not your own.
