First of all i would recommend to not start in the beginning of the song but when the drums and guitars kick in since that's where the song 'really' begins. Second, make streams with the slider to stream tool. You can acces it by clicking shift, control and f while having a slider selected. Second of all the map is not really good it's not aesthetically pleasing and a lot of rhythm choices are weird. Third, what ever this thing is 00:51:519 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7) - remove it. Fourth, Yeah i don't think there's much to say about this. continue mapping this kind of stuff and you will eventually get better.
