the SVs are very poorly done, please spend some more time figuring them out a bit so you can make them smoother in this chart, fluxis has a lot of cool ways to make stuff like this simpler. You're missing comma separated tags as well as proper chart colours, to check if colours work please use default skin to double check, there are also missing sources. while I can appreciate the playfield following the characters and other elements through the chart at time it's relatively poorly done here especially for those who do NOT use the BG video. On top of that the diffname shouldn't have "4k/6k/2+1kSide" in it. on the topic of lane switches, they feel VERY odd in this chart, either oddly done or they just change for seemingly no reason... please resubmit when you have worked on this a little more.

For sake of playability. Please use the new lane switch layout for your 3k and 2k segments and rearrange your layout. I won't be denying this as this can be a simple change.
