Just stick to not attacking the critics and you'll be fine.
FEEDBACK:
:10 That piano/synth/whatever is a little too loud and is crackley. I'd replace it or lower it down.
:23 Those strings are way too high and sound like they are from the SNES. Try lowering them an octave or two and replace the sample (Squidfont Orchestral Soundfont is good, you can find it online)
:35 The drums are really generic, I can tell exactly what directory of the FL Studio default samples you got them from. You can try using an acoustic drum kit sampled (the "Sky Kit" in the free Kore 2 Player you can find online is really nice)
:46 Violin sounds really stiff and bad quality. Violins are hard to recreate on the computer, so I'd suggest finding someone to play it for you (there are lots of really nice people on this website, just post a thread in the recruitment forum and wait a few days.)
1:00 Things get a little busy, sounds like it's building up to something grand.
1:48 NEVER repeat cymbals every bit like for a regular chorus unless you're building a crescendo or something. I'd just have the one at the beginning and then other every two measures or something like that.
Overall at this point you have a lot of things going on, it sounds really crowded. And in my opinion, the maniacal laughter in the background is not needed and really takes away from the feeling.
2:25 There it is, to complete the package. Never, and i mean NEVER, use FL Slayer for electric guitar sounds. You need to ask someone because they're also hard to replicate.
Other than replacing the really low quality sounds you have, the arrangement is pretty nice. It's just from 1:48 on, I feel as though you made that part too long, see what else you can do to make it more interesting after half of it passes.
Other than that, I really like the feel, the mood, and the arrangement!
I'd say all in all this just needs a big production upgrade.
