I feel like you have the offset a bit off, you don't have to use the timing points at 02:09:513 (1) and 02:18:277 (1) if you set your default offset to 53. Also if you changed the offset, don't forget to move the Inherited points, so the sliders aren't all messed up. Otherwise it is a really nice map.
I feel like this map could use some sliders. You could fill in the gaps and you don't have to always focus on the main thing and/or the dominant sound from the song. For exapmle from here 00:29:164 (1) to 00:47:807 (1) there are sounds inbetween the circles.
00:38:471 (1) - I would not use the reverse slider and instead would add another circle at 00:38:862
