[Hitsounding]
I'm personally not a big fan of using custom sliderticks, not that they're banned or anything, but having them on the lower difficulties to make up for "missing" notes caused by more simplistic mapping creates an issue where you are giving "fake" feedback to the player, which can screw up people, especially newbies when they're trying to learn the game.
From the cup until the platter, this problem is really apparent, pretty much everything on the cup, stuff like 00:24:428 (2) - or 00:25:391 (2) - feel so weird because it just sounds like you're catching a fruit that doesnt exist.
It's perfectly ok to skip notes for simplicity sake for lower difficulties, sometimes we have to sacrifice good sounding difficulties for good playability, and IMO this map would benefit of removing the green timing points that change the sliderticks samples and just leave the default ones.
Two problems here:
I highly suggest having contrast between sections of the song by lowering volume on more calmer sections, like the intro, and then have a higher volume on more intense parts, like the kiai.
About Cup and Salad sliderticks: It wasn't until last night where I thought it would fit a bit better gameplay wise and didn't really check how the feedback on hitsounding would be by the time I uploaded.
After what's suggested about Slider Tick Rate for Cup/Salad most ticks should be gone, I'll re-apply hitsounds on them to avoid sampling on slider ticks that are not neccesary.
Will leave open for Cowboy's opinion.
Edit: About hitsound volume. Changed every diff to 40% for intro, 60% for non-kiai and 80% to kiai
You probably should add R・O・N, which is how they normally write the song arranger their name (Especially as you already have RON)
See their own blog how they write it, on the right at Author -> http://stereodive.blog54.fc2.com/
