I suppose I have two main issues.
1: It's a bit "amateur". By that, I mean that the article is formatted in a strange way, with the blocks of text being with different and inconsistent spacing. There are gigantic chunks of text, with opportunities to make it a new paragraph all the time, while there are also paragraphs that end a bit prematurely, and would work best linked up with the next paragraph.
2: It kind of goes nowhere to an extent. So, it's a creature who's saliva can heal or kill, which is decent. But the narrative seems to go nowhere.
I'm afraid I have to 1 this for the moment. Fixing the first issue would certainly make me rerate.
Good luck! And again, I'm sorry.
