This is an NGADM 2015 review.
Okay, so! I make and love drum and bass, so I was happy to see some dnb this round :)
I felt that your intro was really nice. Good chords, nice piano, nice pads, good buildup! Highpassing the kick, good riser, everything. Might have done with some master highpass though because man, the buildup is a good 2db (RMS) louder than your drop :(
I feel that this song had a lot of potential, but the length and production don't live up to that potential. The intro and buildup really had a lot going for them, but your drop doesn't deliver. I'll try and deconstruct why so that I can give you a worthwhile/helpful review.
So there are a bunch of elements that help to make an impact when you go to your drop. I mean, there are more than I can list, but I'll try to cover the relevant ones -
You want to make sure your drop is slightly louder than your buildup
If your drop isn't louder than your buildup, you want a gap or some kind of transitional element to bring in some silence or break before the drop
Your drop should have stronger bass than your buildup (try highpassing the end of your buildup)
Your drop should have more happening than your buildup, unless you're doing a more minimal genre like bounce, big room or even dubstep. This rule of thumb largely applies to transients, if it seems a big vague otherwise.
So I think the issues are that you have no transitional elements, the drop is quieter than the buildup, and it has less bass. Your buildup maxes out around -10RMS, but your drop hits about -12. Unfortunately this is pretty quiet, and it's something of a mastering issue. Another trick you can abuse is turning down your buildup gradually (automate that master fader) by about 1-2db, then add it back suddenly at the drop. Helps the impact.
Covering the bass, your buildup ends with a lowpass. What this ends up doing is cutting down on the highs, and, probably due to the Q on the filter, increasing your mids/lows; so you have more bass than highs. When the drop hits, these switch around - you have a lot more highs and less bass; and the drop sounds "thin." Again, highpassing your buildup and giving your chorus more of a prominent sub (sidechain it with the bass) would go a long way toward helping these issues.
I'd also like to cover the mixing of the percussion if i can, as it's another source of thinness in the chorus. You should use a spectrum analyzer to find the main low frequency of your snare drum and boost it, because right now it's mostly mid-high freqencies and it could sound so good with some punch. The kick is definitely a lot better than the snare, but it could do with more mid-highs.
In regards to mastering, your song is overall pretty quiet, and I think too saturated by high frequencies (during the chorus).
Anyway, I'll try and get to some more positive aspects. Your composition is fairly sound, it's simple but it's quite effective. This could be a really awesome track in my opinion. Your main melody in the first part of the chorus could be a bit less chaotic, but it works well! I also really like the long portamento lead in the second half. On that note, the alternate percussion in the second half of the chorus is great as well. I can see it working to great effect were this song more complete.
When it comes to lack of inspiration, we've all been there, man. I'm there right now, haha. This was a good track, and I think it has a lot of potential (I think you have a lot, actually.) Keep at it, hopefully you get something out of this review.
