The poinits I'm going to cover are pretty specific points in regards to certain ideas I would have as a more experienced mapper, but I think that, if you already haven't, you should check out pishifat's entire youtube channel. He offers a lot of really great explanations about the basics and fundamentals of mapping that, when you learn to fix them early, can be a massive difference in the quality of your maps. I think right now nitpicking and pointing out the finer details is something that wouldn't be helpful to you as a newer mapper, so I'm going to be covering a lot more broader ideas to give you a perspective.
Add tags too!!! Tags are very important to help people find your map as well as helping you keep your own map organized.
Adding stuff like "Vocaloid, Rock, English, Ruuya, Elbo, TakamachiWalk, Lost Forgotten Shattered" is super helpful for finding the map and giving some more detail for the source of the song.
you need combo colors!!!! i know it might seem unimportant but you would be surprised at how much combo colors can affect the feel of the map while you're making it, it's also a requirement for ranking so it's best to just get in the habit of using them
your timing is off, 7136,307.692307692308,4,1,0,100,1,0 is the correct offset for the first timing point
if you go into the Inherited Points window in the timing panel, then hit Ctrl + A on all the green lines and move them forward +29 MS it should fix all of the other timing points you have
audio bitrate is too high (320kbps) if you are unsure how to fix this you can use the audio i have fixed for you:

same timing, etc. just delete the current audio and replace it with this
shoot me a DM if you have any questions about anything I wrote, I'm always happy to help :)
