[General]
I suggest you to find some timing pro to check the timing, I think the current timing is not accurate, but I'm not sure..
[Beginner]
02:31:426 (2) - the current spacing is hard to read imo, try this?

01:11:982 - 01:28:648 - I don't know why you use 1.3x spacing for this part.. it's not an intense part, also the difficulty of this part is too hard for a Normal diff imo, due to the spacing. I suggest you can remap the spacing at this part
[Hard]
HP+1? it's too low now imo
00:44:204 - the rhythm here is odd to me, why not use this one?
http://puu.sh/9WHlt/d1287c710f.jpg02:24:621 (2,3) - put 3 earlier and 2 later(switch the place on time) makes the flow better imo. don't forget to fix the hitsounds if you changed this

HP+1 at least please, same reason as Hard here
01:28:648 - I suggest to add newcombo here to make the following slow-down patterns easier to read
02:14:204 (1) - if you can make the interstice all the same with keeping the symmetry, the slider would be a perfect one
02:31:982 - the slow-down part comes too suddenly imo.. the ticks won't help much on reading
02:45:315 (1) - ctrl+1 and move it 1 gird up, blanket can be better
02:57:815 (4,5,6,7,8,9) - change the sequence, make them going anticlockwise and end the last note at where the current 02:58:371 (8) - is. the pattern's flow can be much better
03:10:176 (2) - ctrl+h for better flow?
03:16:426 (1) - same as 02:14:204 (1) - here
when the timing is confirmed, feel free to call me back then
I know Guy, Charles445 and Faust are good at timing
