Baelin's Route was a short movie that I watched on the yYoutTube channel Epic NPC Man a few years ago.

"YouTube" is the name of a company, so it's a proper noun. Proper capitalisation should be observed (uppercase "Y" and "T").

Actually, it wasn’t so short.

Most of the videos on the channel wasere short comic sketches and the scene wass took place in some game universe.

"videos", "sketches", and "scenes" should be in the plural form, since "most of" implies that there was more than one video on the channel.

For example, in one video, a female player got an a reward for completing a quest.

The phrase "in one video" helps establish context.

The areward was supposed to be an armor, but it looked like a shiny little shiny bra.

"armor" is an uncountable noun. Alternatively, you may write "The reward was supposed to be a piece of armor".

It sounds much more natural to place "little" after "shiny". There's actually a proper order in which we arrange adjectives in English, but knowing what that order is will mostly come with exposure.

The girl was confused and ask an NPS maned the male NPC, who gave her the quest, and armor.

"NPC" is short for "non-playable character". Hence, "NPC man" would mean "non-playable character man". However, "character man" doesn't really make sense, so I'd suggest writing "male NPC".

Also, instead of "a male NPC", it's more natural to write "the male NPC", so that the reader knows you're specifically referring to the one who gave the quest and armor.

The NPC said, “This is an piece of armor.

Again, "armor" is an uncountable noun.

It has all the declared characteristics (and matches to your eyes)."

At thisat moment, a male player came in and got a big piece of black, brutal armor.

He said arrogantly, “I already have the same one”, dropped the armor and ruan away.

Be mindful of the tense! We're still in the past tense here.

The girl happily grabbed the armor and it instantly turned into a shiny little shiny bra.

The end,. All the all action tookonly lasted a few minutes.

Baelin's Route was much longer, but not full meter.

I'm not too sure what "full meter" is...so I just decided to remove it. Perhaps you can clarify what you meant to say in a reply.

Baelin was an NPSC and he was the dumbest NPC in his world, but by the will of fate, he departed to adventure.

"he departed to adventure" is correct, but be aware that "adventure" is actually a verb here! If you meant for "adventure" to be a noun, you can write "he departed to embark on an adventure".

It looked not worse, maybe even betterdidn't look worse than some Hollywood samples I think, mit was maybe even better. Maybe I’ll review it.

A slight reordering will help the sentence flow more naturally.

The award was supposed to be ansome armor, but it looked like a little shiny bra.

You could also say "a piece of armor," or even just "supposed to be armor," but we don't talk about "an armor."

The girl was confused and ask an NPS man,ed the NPC who gave her the quest, an for some armor.

I think you meant an NPC (non player character).

The NPC said, “This is an armor."

It has all the dneclaredessary characteristics (and matches to your eyes).

This sounds more natural. Declared would refer to some specific characteristics about the armor that had been previously stated, and even then, something "stated" would probably sound more natural.

At this moment, a male player came in and got a big black brutal piece of armor.

"Brutal" sounds a little strange here. In what way was the armor brutal? Did it "look" brutal? In that case, it's more natural to call the armor something like "menacing." Brutal generally describes actions, unless you say that something "looks" or "seems" brutal.

He said arrogantly, “I already have the same one”, then dropped the armor and ruan away.

"Then" isn't absolutely necessary here, but sounds more natural.

The girl happily grabbed the armor and it instantly turned into a little shiny bra.

TIn the end, the allall of the action took a few minutes.

I think this is what you meant here.

And it, the video didn’t look cheap.

It isn't clear what "it" refers to here.

It looked notn my opinion, it didn't look any worse, and maybe even better, than some Hollywood samples I think, m. Maybe I’ll review it.
