Firstly, red lines ain't for SV adjustment, you have green lines for that. Red lines are rather for adjusting BPM to sync with the song, and the first one with the BPM of 200 is enough.
Secondly, the whole experience in this map is just mediocre. The only impression I got from this is just "fast sliders go brrrr", everything is just chaos without any coherence or consistency at all. No conscious concept, no emphasis, no visual/pattern arrangement, just some fast sliders. I'd suggest looking at other tech mappers to know how they come up with their choice in mapping, how it correlates to the song, how playability is considered, and then try to apply it to your maps.
Also, rather than posting a single thread here and just wait for someone to answer, you can just post your map on
Modding Queues to have more chance people will take a look at your map and give feedback from it. There are way more people who accepts new mappers' map than here, and a handful of them being already experienced mappers.
