Hi! Welcome to the world of beatmapping.
And congratulations on your first beatmap.
Anyways, I did not checked the whole song since I noticed timing is kinda off.
Try using this one.
BPM - 140
Offset - 11996
Don't forget to resnap and recalc. (read the glossary if you don't know what are those terms are)
I suggest taking some of your time to read the FAQ for:
Distance spacing
Distance snapping
You REALLY need those two in order to make a consistent beatmap. Well not "really" but at least those two are the basics.
