I hope it's better than the first i wrote
Did you write the door SCP yesterday? If so then you've not really taken on board any of the suggestions made yesterday. Your tone is still very much about the wacky antics of the Foundation, and although this may be seen on some of the older entries, the newer entries should be more formal in tone. Also the idea of a Foundation agent suddenly causing everything around him to stick to the ceiling is a bit daft, especially as the radius you've blanked suggests that it's at least 100 metres, which is far too large to be sensible.
Also, there are several spelling mistakes (were/where, allowed/aloud) although they're homonyms so a spelling checker might not have picked them up.
All in all I don't think that you're quite ready yet in terms of the tone of the article, I would recommend reading some more SCPs and getting a feel. You can be a member and never publish an SCP at all, so there's no race to get one written. You're doing the right thing by trying stuff out in sandbox and getting feedback, though. If you'd put this straight up without sandboxing (Which an awful lot of new members do) it could accrue downvotes purely on the fact that it wasn't drafted first.
