Hi please tell me if you like it or not :D

It was a heavily foggy night , Clarence could not hear anything behind him, neither the steps of the creature coming closer, nor its blood-stained breath. The beast just appeared in front of him, and he realized that he was hopeless trapped. Gaping horrified at it the terrified man, stammered; finally he could scream, then, just the silence, the forest recovered its tranquility .As soon as the first morning beam touched his face, the blue eyes of a distracted man, peered the open sky . Not only, could him not remember what was he doing there, But also he did not know who was he. Extremely confused , he try to stand up, but a strong pain in his right leg, forced him to remain on the floor. The wound around his leg was quite deep and wet. Although he understood that he had done it recently, he was not capable of remembering the way . Actually, Clarence had forgotten how the hard-edged fangs of the creature had broken his skin and cursed him forever.

UPS sorry i did not see my other post if you want to block it is ok SORRY AGAIN

It's alright to begin with, but there's a lot of grammatical errors, and a some of the sentence structure is awkward and takes away from the flow of it. I can tell it's about a werewolf or something of that nature, and it makes for a fairly decent prologue, but let me offer some criticism:

"It was a heavily foggy night" This description is good, but just a little awkward. Using adverbs can be a little confusing sometimes, so maybe this could be something like "A heavy fog had settled in the night" and then your transition with your character should have an "and" before it just to make it sound a little smoother. "A heavy fog had settled in the night, and Clarence could not hear anything behind him." End the sentence there, otherwise you'll have a run-on.

"neither the steps of the creature coming closer, nor its blood-stained breath." Alright, now you're trying to appeal to the reader's senses with some imagery, but you're mixing between a sound and a smell, as well as sight. That's kind of awkward. I suggest something more like: "He was unaware of the steps of the creature coming closer, as well as the smell of blood in its breath."

"Gaping horrified at it the terrified man, stammered; finally he could scream, then, just the silence, the forest recovered its tranquility ." a bunch of grammar errors in this sentence, but once they're fixed, it'll sound pretty good. I suggest adding a "..." or two in there so the pauses are more dynamic. Commas can make a sentence sound choppy. "Gaping horrified at it, the (delete the unnecessary adjective) man stammered. Finally he could scream...then there was just silence, and the forest recovered its tranquility."

"As soon as the first morning beam touched his face, the blue eyes of a distracted man, peered the open sky . Not only, could him not remember what was he doing there, But also he did not know who was he." again, there's a lot of grammatical errors and awkward sentence structure. Very good description and imagery though, but I'll fix it up for you: "As soon as the first morning beam touched his face, the distracted man's blue eyes peered at the open sky. Not only could he not remember what he was doing there, but he did not know who he was."

"Extremely confused , he try to stand up, but a strong pain in his right leg, forced him to remain on the floor." More grammar errors. I've noticed that you tend to use a lot of unnecessary commas. Fix those, and it'll be perfect. "Extremely confused, he tried to stand up but a strong pain in his right leg forced him to remain on the [ground]." I put "ground in there since your character is outdoors, it'd be a better word to use than "floor".

"Although he understood that he had done it recently, he was not capable of remembering the way . Actually, Clarence had forgotten how the hard-edged fangs of the creature had broken his skin and cursed him forever." Again, the wording here is a bit awkward because of a few grammar errors. "Although he understood that he had received the wound recently, he was not capable of remembering how. Clarence had forgotten how the hard-edged fangs of the creature had broken his skin and cursed him forever."

If you just correct all the things I pointed out, you'll have yourself a pretty decent sounding prologue to your story. I recommend using a thesaurus if you have one in your word processor. Thesauruses are really helpful when you want to make your writing sound prettier. I constantly use it while I'm writing. Good luck, and i'd be happy to help whenever you need it.
