Here comes review number 2.
First of all, mashups aren't your work and aren't allowed on newgrounds. I suggest taking it down yourself so that you don't get your whole account deleted by forcing an administrator to take it down for you.
Now that that's been discussed, your song needs a lot of work on many fronts:
Reverb once again- Way too high, muddies the sound. lower decay to a maximum of 2 seconds or lower the wet signal.
Melody- Repeats throughout the whole song. I suggest switching it up.
Voice sample- Illegal according to NG's terms of service, unless you have explicit permission by the artist to do such a mix with that song.
Sound effect- that sound effect at :22 does not match the bassline nor the melody, considering it's a C note and the song is composed of these 4 notes: D-Eb-F-G, so it should either be playing G or D. Hell, even A would be a better fit.
Bassline- most of the time, there's no bassline, but when there is, it doesn't fit the melody at all.
Synth- I hardly lodge this complaint, but it's too er, well, blockish. It's like the attack and release parameters are set to the lowest values possible. Also, the saw may be a little too detuned, making the note a little hard to discern for me anyways. (perfect pitch is a bitch when the instrument is playing several pitches at the same time....)
The drums aren't all that spectacular.
I'm sorry, but I can't help you that much, there's too much to work on and this isn't even my genre of choice. Feel free to PM me on specifics, but in the end experience will do you much more good than my words will.
