the rhythm in the map doesnt have much variation, and it could use some to represent the song better. lots of it is 1/2 circle spam with an occasional slider or stream thrown in: e.g there isn't anything differentiating this section 00:00:460 from this section 00:16:644. try to incorporate variation that fits the song, which you can do with stuff like rhythm, object spacing, and slider velocity. you can think about following specific instruments, or the intensity of the song. this will make the match the song better, and make it more interesting to play.
make sure you're mindful of putting down your rhythms accurately. you often have things off by one 1/4 tick accidentally (e.g 00:03:716 (3) starts 1 tick too late, 00:15:065 (1) ends 1 tick too early, 00:27:400 (1,2,3,4,5,6,1,2,3,4,5,6,7,8) is off). you don't need to go through your entire map and fix everything but try to be careful with future maps bc it makes it much harder for players to acc.
