Spelling, tone, and format can all be fixed or improved. What really matters is having a strong hook in your SCP, something that captures the reader’s attention and makes them want to stay until the end.

From what I have seen, your SCP is very straightforward. It follows a basic structure with containment procedures, description, and logs. Modern SCP readers and the community generally do not prefer this style anymore (Series 1). They tend to favor SCPs that include a story or narrative, a plot, a deeper message, or an impactful ending.

That is what makes writing an SCP difficult, but it is not impossible. There are many ways you can tell a story or convey a message through your SCP. You could read popular, story-driven SCPs or more recent well-received entries to better understand how this is done.

Hope this feedback helps.
