(You said up to the first chorus, but it seems like you have a whole map?)
Edit: I just realised you said you finished it all in your edit
I'm a new mapper myself but some of the things that I thought were not so good:
. Some of the streams have very awkward shapes such as the one 10 and 12 and 20 seconds and 1:33 in. The stream at 2:34 also seems a little bit bad at the end of it (when it goes directly down); you could probably turn that last part into a slider to show how the guitar holds on one note until it fades (but that might be a long slider, maybe it could be cut earlier).
. Slider shapes also seem a little strange - I think one of the main issues is that the slider velocity is quite fast, too fast for the bpm and you could probably achieve a similar effect in terms of sound design using a simpler shape. Some sliders I find issues for example are 8 seconds in (the two curved ones) 10/19/38 seconds in (could be smoothed out using nodes much more efficiently since you only need like one), 18 seconds (zig-zag one)
Also maybe you could add kiai time?
Edit: Add hitsounds
Edit again: after the first break, you should try to calm all the mapping,at around 1:26-1:27, I don't think you had to use the streams; you should try to use streams and jumps less overall as it begins to feel (for me at least) a bit too repetitive
I apologize for typing so much, I'm just used to writing in detail xD.
