Hi SFG! Just a general overview by now:
Background: You'll probably need to resize it to 1024x768 (current size is 1280x960).
Inconsistency in AudioLeadIn: [Easy] has 2007 ms, while the other diffs have 1996. Consider putting all of them at 2000 or so.
Unsnapped sliders: I detected a lot while checking the CTB diff. Here you have the list with all of them that AIBat detected, and make sure to snap them properly!SPOILER[Hard]

I understand it's still WIP. Are you planning to use "___aph___sorrow_made_you_by_ephemeraldelusion-d496oco.png" somehow?
I suggest you to make a softer transition between the current images. For example:
00:09:289 - This is the point where the singer states "Don't go". Here you can start a fade-out of this image, and a fade-in of the next one...
00:10:178 - Until here, where the singer says "Simple and clean"
01:08:903 - Same as before, you can try the same effect.
01:09:496 - ^
02:10:297 - ^
02:11:187 - ^
00:57:633 - At this point, where the next chorus is about to start, you can start the fade-out of the image slowly, until turning the screen black.
01:00:005 - And here, it'll fit a sudden appearance of the image (but not so sudden as it is atm orz).
02:00:510 - Same as before, you can try the same effect.
02:01:696 - ^
02:37:287 - ^
02:39:659 - ^
There are some other occasions where you'll need to include a softer transition between images, for the rest of the choruses afterwards.
[CTB]
OD+1: To match it with the AR.Combo Colors: Make sure to put the same as the osu!standard diffs. There's no need to introduce another one.00:07:212 (1) - This spinner is too close to the previous (unsnapped) slider. Probably it'll be fixed after snapping it.
01:17:652 (3,4) - And here, the note is inside the slider-body orz.
02:00:510 (5,6) - ^
Make sure to fix all those slider ends, cos I can't check the diffs properly right now ;__; AR in the CTB diff might be changed, gotta check it with other players.
