SCP Foundation

The technical writing here is solid, with good clinical tone.

The containment procedures all make sense, and again they're good in a technical sense, but I don't think you need this much detail. It's realistic, but it makes the article drag a bit. For example:

Following completion of the experiments, all plant-based materials that are either confirmed or suspected to have been exposed to SCP-XXXX are to be incinerated. Remains of living plants are to be disposed of by counter-occult specialists familiar with ecliptic residual distortion energies (ERDE).

Groups of potted plants are to be placed in all rooms adjacent to SCP-XXXX’s containment chamber and monitored for the si[gn]s of SCP-XXXX’s primary anomalous effect. Monitoring is to be intensified during the night of a new moon and the night of the winter solstice.

Personnel entering the containment chamber are to wear clothes made purely from non-plant based fibers. Any objects made from plant-based materials, such as jewelry containing amber, are to be discarded before entering the chamber.

could be cut down to something more like

"The exterior of SCP-X's containment unit is to be surrounded with potted plants. Any plant matter showing signs of SCP-X exposure is to be incinerated. All clothing and other items carried into SCP-X's containment area are to be made of synthetic materials."

without losing much. The details about the residual distortion energy and the solstice don't come back into the draft in any meaningful way.

A lot of the elements here seem thrown in at random like that, so the article as a whole isn't very cohesive. You've got the mutation of plants, the addictive property of the fruit, the humanoid creature, and a vague reference to eldritch gods; none of it seems to mesh thematically and it all ends up feeling pretty generic. None of the addenda are badly written, but none of them really add to the story either - the one about the person eating the fruit felt particularly bland and unnecessary (a single sentence somewhere noting that its fruit is invariably reported to be better than any non-anomalous species would accomplish the same thing).

I think this would be a lot stronger if you cut it down; I'd take out the addenda with the person eating the fruit and the one about the seven flowers and focus on the creature that lives in there and what its relationship is to the eldritch god hinted at in the end. Is the thing trying to help humanity by holding back some evil that's going to come out of the tree? Or is it trying to spread it? Leaving some kind of mystery there might help.

It is actually something of both. On the one hand, the entity wants to break the chains in order to release the human from the grip of the other entity but at the same time, it wants to envelop the human with its vines to claim him for itself.

The base idea behind this was basically a deal with an eldritch abomination in order to escape a previous deal with the devil, without realizing that the new contract partner was even worse than the previous one (you can see this more details in the supplementary tale).

Therefore I was actually aiming for this questionable nature of the "moon-vine entity". Yet at the same time, I tried to hint at its true malevolent nature (its servant tortures plants to the point that they can scream, the smell of decomposition and the dead nature of its tree, the mentions of the D-class about the "forbidden fruit" and being expelled from paradise and lastly the mention of the "Green Sahara").

The final conclusion I wanted to hint at was that the entity actually caused the end of the Green Sahara phase and turned it into the desert it is today.

In retrospective, I definitely have to adjust the article to better hint at this conclusion.
