However, they spent over an hour to drawing my request, and of course the drawing was amazing.

There are good things that I appreciate and I should feel happy about, but there are also things that make me feel negative and they easily overshadow good things.

So, I thought my 2022 was going to end while I felt like shite.

However, because of Akka’s chill live-stream with Jjazz music and their generosity and kindness to use artistic skills for me, merely one of the viewers, without hesitation, I could end my 2022 in a really good mood.

On the night of the last day ofNew Year's Eve 2022, I was watching a live-stream on Twitch.

Similar to 大晦日 in Japanese, you can say the last day of a year is "New Year's Eve."

The streamer was Akkalime, a Filipino artist / VTuber who drewaws and madekes live 2D models.

Since this VTuber is still doing this line of work, past-tense wouldn't fit here.

I like watching art live-stream by artists in general, and Akka is a really nice person and one of my favorite streamers, so I visit their live-stream as much as I can.

I like watching art live-streams by artists in general, and, combined with the fact that Akka is a really nice person and one of my favorite streamers, I visit their live-stream as much as I can.

The corrected sentence is fixed, but I personally think it is too long and clunky and would split it like so: "I like watching art live-streams by artists in general. And combined with the fact that Akka is a really nice person and one of my favorite streamers, I visit their live-stream as much as I can."

On their Twitch channel, there is a redeem called “Doodle” that makes themwhere they will draw something by a request of a viewer.

"Make" makes it seem forced (though it sort of is) so I softened the language this way. I am also not entirely sure, but I feel that "redeem" might not be the correct word. I don't go on Twitch, so I wouldn't know. But I think I would phrase it along the lines of "redeemable option by donation."

I redeemed it and requested for them to draw my Live 2D character.

This was the first time an artist exceptbesides the illustrator of my character drew him, so I was really excited.

The redeem was called “Doodle”,” so I expected a simple drawing.

Any punctuation that follows something in parantheses will always go inside the parentheses.

I guess even if they had drawn a simple rough sketch in five minutes, I would have been thoroughly impressed enough and happy.

I feel that this would be better word choice here.

However, they spent over an hour to draw my request, and, of course, the drawing was amazing.

I noticed that the other correction said to avoid using "however" in the start of sentences. But that simply isn't true. It is certainly taught this way in the American education system in my experience, but it is not true at all. Forcing yourself to confine to that 'rule' will sometimes ruin the flow and overall nuance that you originally wanted to convey.

There are surely many other conjunctions in English that have this idea of using them to start a sentence being no good. When you encounter any of those, I'd advise for you to do some research because many of them are surprisingly okay to use in that way.

I have been in a bad mood recently.

Both 'recently' and 'lately' are fine. I hear both 'recently' and 'lately' in the US. It's not a matter of fact of one being more used in the US. They do have slightly different meanings, however. I probably can't give a super thorough comparison here, but a quick google search will probably help. Here's a stack exchange post on the topic: https://english.stackexchange.com/questions/32571/difference-between-recently-and-lately

So, I thought my 2022 was going to end while I felt like shite.

"Shite" is definitely more UK English. "Shit/crap" would be more American English.

HoweverIn the end, though, because of Akka’'s Jazz-filled chill live-stream with Jazz music andalong with their generosity and kindness to use their artistic skills for me, mere without hesitation, one of their mere viewers, without hesitation, I could end my 2022 in a really goodreat mood.

Changed the transition in the beginning since you already used 'however' before and 'good' to 'great' since you also used that two sentences before.

I gotrew to like them even more.

You mean New Year’s Eve (December 31, 2022), right?

On their Twitch channel, there is a redeem called “Doodle” that makes them draw something by a request of a viewerper a viewer's request.

I redeemed it and requested them toat they draw my Live 2D character.

"To request that ..." We don't often use a direct object with it because it's often implied or inferred.

This was the first time an artist, except thefor the original illustrator of my character, would dreaw him, so I was really excited.

The redeem was called “Doodle”,” so I expected a simple drawing.

However, tThey spent over an hour, however, to draw my request, and, of course, the drawing was amazing.

We avoid using "however" at the beginning of sentences in writing.

凄い！

Your sentence is correct but this is how we say it in the US.

However, bBecause of Akka’s chill live-stream with Jazz music and their generosity and kindness to use their artistic skills for me, who was merely one of their viewers, however, without hesitation, I couldan say I ended my 2022 in a really good mood.
