Hey, just a few tips to get you started.
First of all, you ARE gonna do a real easy right? Obviously that was just leftover from a previous attempt, but since you are going to want multiple difficulties if you want it ranked, you should fix it up (ie, do it over again
)
And with all of the difficulties, you will want to turn on Distance Snapping, to make sure notes that are spaced the same on the timeline are spaced the same visually. You did have some interesting jumps in hard, and the occasional jump is ok
if you know what you're doing. For now though, I would just go through the distance snapping on first.
Also, I would have your bpm to 135, it just makes more sense this way.
Were you planning on mapping more of the song? Keeping it that length for Easy would be ok I think, but for Hard I would map at least another minute and a half or so.
Go back and try out my suggestions then get back to me. Good luck!
