Easy:
00:16:627 (1) - Move so it's not touching (3)? Also, move the center node up to make it more symmetric.
00:25:913 (2) - If you're trying to wrap this around (3), it looks kinda ugly. Try using more nodes than just 3 for a better, more circular shape.
00:37:163 (1) - Since this is easy try keeping the beats on white ticks- move to 00:37:341.
00:47:341 (1,2,3,4,5) - Make this symmetric? Like:
00:50:198 (6) - either put this in the middle of 1 and 2, or stack it with 1.
01:05:199 (3) - Not symmetric
01:25:377 (1,2) - 1/2 beat back? see 00:37:163 (1).
01:27:341 (1) - That's an ugly way of making a slider-
look here for some suggestions.
01:56:627 (2) - A bit too close to (1)
01:59:841 (2,3,4) - Shift+Respace these notes using the 45-degree snap for perfect spacing and a linear pattern
Normal:
Slider velocity of 2 might be a bit much.
00:10:734 (2,3,4,5,6,7) - work on making this into a more circular arc
00:11:984 (8) - Position in the center?
00:23:056 (1,2) - Too pointy
00:53:413 (1,2) - asymmetric, try remaking these.
01:30:020 (4) - Try to make a prettier slider? Ask around #modhelp for an expert to guide you through it, spirals are really hard to do.
01:32:520 (1) - Position and center? (and adjust others accordingly)
01:37:341 (3) - Sounds noisy, try lowering the volume
Generally the placements of beats in time was pretty good. However, at times I didn't feel like there was a coherent style in your choice of patterns, which can make things confusing. Overall pretty good, though you might want to consider making another difficulty or two. Starred!
