Okay, here we go. Gave this a quick read since it's late and there are 15+ other unanswered threads in the forum right now.

Initial Reaction: The image is creepy, but it's too big and obviously has the artist's signature on it. Not only does it seem unrealistic (why would the Foundation use something that's obviously not an actual picture?), it might also land you in trouble with the creative commons licensing the SCP wiki uses. Also, the relative short length of the sections makes me hesitant to expect the piece to be high-quality, since it seems to be similar to a lot of creepypasta-esque "flavor of the week" monsters we see deleted off the mainsite every day.

Containment: Excessive and overcomplicated. 10 meters is about 32 feet, taller than a three-story building. That "room" you have is essentially a warehouse. Furthermore, there's no reason here to require that cubic chamber, or the steel. The periodic coating of baking powder doesn't make sense given that there are plenty more non-stick materials one could coat the walls of the cell with that wouldn't need periodic application. And so on. I recommend reading this guide on containment to get a feel for how to write more logical, resource-conserving procedures.

Description: Doesn't sound like a professional researcher's work at all. You start off with essentially a meaningless sentence—"origin is unknown" doesn't really need to be mentioned, since it can be assumed if nothing is stated about the origin, it's either unknown or mundane enough to not merit detailed mention. The rest of the section is just typical horror video game stats listing of the things various limbs and extremes like "two legs that stick to anything" (so… do the legs stick to themselves? Can the Foundation overcome this thing by tying its legs together?). Keep in mind that as the author, you know the entire story, but the Foundation needs to have discovered what it knows about the SCP object through observation and experimentation. You'll need to convince your reader that someone with no prior knowledge whatsoever of the anomaly managed to somehow figure out (not magically know!) all the information you've got in the article.

Overall: Lots of issues, especially with basic writing. "It's" means "it is" or "it has", and is not the possessive word. For fixing simple issues like this, I highly recommend running your draft through a word processing program or writing assistance tool like Grammarly (which is available for free).

This is definitely nowhere near ready for the mainsite, and I've only covered a few of all the nitpicks I could have made.

I suggest reading over this essay on common SCP pitfalls to get an idea of what elements to avoid putting in an SCP article, and etting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft.
