There are no hitsounds in Speed Run.
Approach circle makes it hard to play, I suggest killing it along with the spinner circle. (It's not fully circular or centered either. =s) If you do want to skin the spinner, skin all three elements though, not just one. Otherwise you'll get conflicting skins unless you force to default or something like that. Which I can't say I recommend.
"Combobursts should not be wider than 500px." "Backgrounds/Images should be at a maximum 1024x768 pixels, though 800x600 recommended."
The HP Bar is deceptive as it won't show you're losing HP unless you're under halfway. Fix this by making it longer. I think cropping the image works too as it only goes by the image width and you have blank padding which should be causing this, but I'm too lazy to fire up Photoshop and check. Just crop/resize. (There's too much whitespace either way.) Also the HP colour doesn't fill the right corner of the HP bar properly, there's some black space, fix this. Resize the scorebar-ki/dangers to 1x1 pixel.
You have two .osb files in the folder, delete one.
General
Set a preview point for all three difficulties.
Add tags and keep them the same for all three diffs cept for guest tag-diff. aka Sonic's only on one atm. Missing Thunderstorm tag.
The 2 mp3 thing is kind of iffy in general, so you need to be careful when doing that. Reid's mp3 is over 7mb, I suggest resizing it. ~5mb would be good.
Odd that you doubled the BPM for those two diffs, but it works.. I think. Having trouble playing these accurately with the spacing, lack of hitsounds on one, volume, and approach circle.
As a sidenote, your volume's a bit high imo in some sections, this song's an instrumental and the beats aren't prominent, you don't need loud hitsounds, it'll drown the song out.
Thunderstorm's Walk
01:47:384 (4,5,6,7) - Not stacked properly.

Either cut the mp3 or map further. You have a minute of nothing at the end. This ties in with the filesize issue.
I'll just leave it at this for now.
