Nice, just some things you might want to consider (just suggestions though):
Basic:
01:01:69 (1,2,3) - If you're going to do this, you might as well put finishes- sounds better IMO, and makes sense due to the jumps.
01:11:88 (1,2,3,4,1,2,3) - For this part, I would either make them all jumps, or all regular spacing, but eh, that's just me.
Difficult:
00:21:69 (8) - I would move the slider end so it's farther away from (1).
01:08:24 (8) - ^
Expert:
No comment, let someone who's good at osu! mod this. ;P DDR Xy indeed.
