A decent attempt at writing. Your descriptions are rich and detailed, and the plot is very intriguing. However, apart from the occasional grammar mistake here and there, you committed some basic writing errors that prevent your writing from really shining.
1)
Awkward expressions. Quite a few of your sentences (in fact, most of them) are poorly worded, and I've quoted two sentences below:
Damienthedevil wrote...
Her eyes belong not that to a human...
it was a pain like no other he felt before....
For example, I'd write the first sentence as "Her eyes were not those of a human", and the second one as "it was a pain he had never felt before". These awkward sentences make your writing look unpolished, so I'd suggest proof-reading your work after you write it to catch errors like these. Also, while some of your sentences were worded fine, you might want to improve them by using more specific and meaningful adjectives and verbs.
2)
Tense agreement. It's very important that you keep your tenses consistent. You should stick to either past or present tense throughout, depending on whether it's present narration, first-person, third-person etc. Since you are narrating a scene that has happened (in the fictional world), you should be using past tense throughout. This quote below is one example in your writing where you failed to keep tenses consistent:
Damienthedevil wrote...
The girl brought her face close to the young man's neck, so close the breath touched his neck. Then, she suddenly open her mouth and reveal fangs, long fangs, and sink those fangs into the young man.
Again, there are quite a few of these and it really hampered your writing.
3)
Punctuation. You tend to have
way too many strings of dots ("......."), and what it does is confuse the reader in terms of how your prose flows. You can substitute your dot strings with commas or semicolons depending on the nature of the clauses you are separating.
So those are the major errors I spotted from a quick readthrough. I'd also suggest that you add descriptions of how they talk (ie. "Lucia said confidently" or "Keith retorted"). These can really spice up the conversations if done well.
These were just the main things that stood out to me as I skimmed through your writing. I wish you luck on your chapter; I know how difficult it is to overcome writer's block, and it seems like you're doing a good job with that.
