Ok, I'll just point general things things over here to make your map flow much better than it actually does.
-Easy, Normal and Hard, they all have sliderspeed 1.4! Go check the alredy ranked maps and look at their sliderspeed. Easy usually has a lower sliderspeed than all the other diffs, and it increases as you make the diff harder. My suggestion: Keep easy at 1.4, make normal use something like 1.5 or 1.6 (you'll have to check your sliders after you do this), and if you do are planning to remap Hard as Odaril sugested (wich I strongly recomend too), use slider speed around 2.0 or maybe even higher
-Hitsounds: Use this pattern, no exceptions if you want to keep it safe.
This means: clap on the 2nd and 4th beat. You must also add finishes at the start/and of a chorus or a verse (to give emphasis to the change) and you may want to add whistles everynow and then whenever they fit, but make your claps as I stated above and you'll be ok.
-Grid snap: Try to use it at lvl 3.
-Stack your notes. To stack a slider/circle, just create the slider/circle directly under the place you want for it to stack.

Ok, try to avoid using notes on the red ticks. Beginners won't hit them as much as you'd expect.
Also, why does this end at 01:58:720 ?? It's a really akward place to end the map.
00:40:113 (1) - This slidershape is really confusing to newbies imo.
01:11:523 (1) - What? This note is not snapped either to a red tick nor to a white tick.
-Normal:
I warn you, this is too long and won't get ranked, just approved. If you want this ranked, end this earlier (on a place that makes sense) and then cut the mp3.
00:50:518 - Why did you place a break here? be consistent, if you added spinners before, add one here.
01:19:712 (1) - spacing
04:14:534 (1,2,3,4) - Patterns like this don't make any sense
04:57:607 (6) - avoid hiding your sliders under combobursts
I won't mod Hard, as it is a "Hard rock" version of normal.
Also, I won't star this, even though I LOVE the song and the band, because it needs a lot of work.
