[General]
The difficulty spread is kind of worrying. You have a normalish Easy, HHII. It's really top heavy - especially when you have all 6 difficulty slots taken up, and I'd really like to see something to bridge the gap between the pete diff and Siruru's diff. This is really guest diff heavy already considering you only have one of your own. I would prefer that you make another difficulty of your own and try to bridge that gap. You would have to drop a guest difficulty though. :/

Your difficulty settings are way too low. Raise HP drain by 2, and OA by at least 2.
Plays fine, though you could probably lay off on beats a little bit to reduce the star rating. Like maybe instead of having a shorter slider at 00:32:095 (2) - , turn it into one long slider with a repeat at 00:33:407 - (that reduced it by .08 rating just right there)
Try to experiment with that, perhaps.

At least raise HP drain by a couple ticks.
00:29:657 (2,4,5,6) - Maybe reduce stack leniency by one so you don't get a giant stack here? If you do, though, you may want to manual arrange the 4, 5, and 6 down and to the right a little bit so it doesn't look too weird... Bah, just a minor thing. Don't worry about it.

02:14:095 (1) - Can you make this gradually fade out instead of just suddenly being low volume? Just use a timing section every white tick or so.

There are a bunch of unused uninherited timing sections in here. Please delete them.
01:38:095 (1) - This slider as a catmull is pretty bad looking. I'd use bezier.
01:41:095 (1) - ^
02:14:095 (1) - Same comment from vincerio's fade out.

Please use the same combo colors as all the other difficulties. The BG color scheme isn't any different compared to the rest of them.
01:51:407 (4) - There a reason you used this slider instead of the normal rhythm you used the other three times this part in the music came up? Felt kind of weird.
There's so much more you could do with the hit sounds. Try using some normal soft whistles in there for emphasize vocals or something.
The maps themselves are mostly fine - it's just the top-heavy difficulty spread that's hurting the set as a whole in my eyes.
