Here is 8 good reasons to use Sapphire's BG.
1) Your current background directly mentions a different song, unless Equestria Girls is Ponyville's rave of the century. Wouldn't surprise me.
2) Sappha's BG shows the apparent singer of the song parodying the Katy Perry original, which fits, considering that's what the song's doing. Speaking of which, 'katy perry' 'snoop dogg' and 'california gurls' should all go in tags.
3) SapphireGhost is a dirty thief and should be punished. I stole the BG from
this rather artistically skilled guy and then he stole it from me when I showed him my half finished WIP of a difficulty for this same song. Unbelievable.
4) It's wonderfully disturbing.
No, just kidding, I don't care what you using, posting because I am very bored. And because I felt like saying I consider ztrot's hitsounds to work with this as well as any other song, and they sound a bit monotonous, soft and not really fitting of the lively, summery sound this song gives. Except the whistles, good choice there. Now that I've shown my opinion, I feel like a prick, so I will now mod your WIP map, which is quite a rarity. Ha ha ha!
But maybe they're okay. This is the longest premod I've ever done.
General:- Seriously, I suggest you use a more related background rather than just Vinyl Scratch. Doesn't have to be Sapphire's. It's still less disturbing than ztrot's avatar plot though.
- The metronome doesn't seem to fit the intro section, and seems like it should start at 4525. Yo' choice though of course.
ztrony:00:41:005 (6) - I thought this felt a bit lacking without a slider whistle, and the clap at the end rather unnecessary. Do what you want with it, though.
00:48:445 (2) - In my opinion, a 'whistle' works nicely here. Since they match up perfectly.
00:48:925 (1) - Likewise, ^.
00:58:285 (1) - A thought about a finish here, but do you think it would be overdoing it slightly?
01:18:685 (5) - Clap on the repeat?
01:23:725 (6,7,8) - Maybe you could replace these with a pattern similar to
this. The 1/1ness works as well, this is just an alternative.
Oh my god this is a hitsound mod I never thought I would
Hard:00:35:005 - This feels a bit like an empty space, as there should be another triple here, considering you mapped the one at 00:34:525 (4,5,6).
00:38:125 (7,8) - Variable stacks on slider ends feel a bit uncreative,
00:50:605 (1) - I recommend a finish on the start of this, to fit with the chorus starting very well.
01:17:725 (1) - Finish on this?
01:29:005 - You could add a hitcircle to be consistent with zedtrot's difficulty.
I'll mod this notshittily and star it when the other difficulties get done, bro. Sorry if I came across a bit nitpickyish with the hitsounds so far. And Sapphaha's difficulty is nice. Good effort so far
