First problem happens right in the beginning: 00:00:482 (1,2,3) - These notes do not start on a long line, or a measure start, I don't know if this could mess up your map or not but it does seem it'd be best to start on a measure start, try to change it, I'm not a genious with offset but I'm sure you can figure this out, but I don't think it'd be completely bad for your map, if it seems to work well do this for all difficulties!
Insane
00:06:705 (6,7) - These notes are sort of a bit weird, I suggest taking a look at them and maybe making a different pattern, since they could be a bit confusing.
There weren't really any flaws with this map, I thought it was very fun and amazingly good for your first map, kudos to you sir/ma'am (idk your gender)
