0:06:059 (1,2,3...) - maybe make that stream more curly, so the first slider isn't that high? it's quite too high, and might cover with HP bar for some people.
0:23:886 (5) - spacing, move it higher a little
0:26:163 (1) - new combo, that note is pretty hard to read without it.
0:30:169 (2) - once again, spacing... please take a look through the whole map for patterns like that, they ain't looking good :c
0:45:797 (3) - new combo, I guess?
1:22:865 (1,2) - maybe swap those notes? plays a lot better for me~
3:03:074 (3,4,5...) - pretty much like at the beginning, this slider might cover with HP bar. make the stream more curly.
3:05:273 (1) - move the timing section a little later, so there's a hitnormal at this place too
3:37:943 (1) - (nazi) I'd end the map with a single note, not with a slider. :p
and yeah, move it to Pending, if this difficulty is the only one you're going to implement in that mapset.
pretty amazing, as usual :3
