Hi there, I saw your post here: http://www.newgrounds.com/bbs/topic/1383267 and figured I would write you a constructive review to help encourage you, and give you some advice from the perspective of someone who has been posting tunes on Newgrounds for a few years now.
First of all, I would like to mention that review scores are subjective, and can be modified for many reasons. For the most part, from what I've determined from experience, if people like your music they will vote it a 5. If they don't like your track, they will likely vote a 0. There is much fewer users who vote in the mid-range, as it influences the posted score less.
Secondly, I would like to mention that a review score doesn't provide much purpose other than a vague guide as to how a user was feeling when they listened to the sounds you produced. Basically, you might get put slightly higher up on the "high rated" charts, but unless your song is Paragon-X, Rig, or Mrmilkcarton good, it won't make much of a difference in plays or downloads.
Alternatively, posting positive reviews with cognitive thoughts and reflections helps you to grow as a musician, and learn a little bit more about what people were expecting. In addition to that, if you write other artists a lot of useful reviews, you get more reviews, and they tend to include more complete feedback.
For example, have you tried posting your songs anywhere other than Newgrounds? The typical response from a randomly selected user is usually something along the lines of "This song is catchy, but has no lyrics, thus i do not like it".
Anyways, enough introduction, let's get to your review!
I took some time to listen to a couple of your tracks, but this is the one I've decided to review for you. It's a catchy tune, with high quality synths. The EQ sounds alright, but every musician knows you can always spend more time mixing / panning things to sound more spaced out. The beat is structured well, but it loops several times within the (short) 2:16 duration, without much alteration or creativity outside of the loop. Try making a couple drum patterns, and doing a sequence such as 1 2 1 3; or extend the drum loop to either 16 or 32 beats to allow for more creativity. The hi-hat sounds alright, but gets repetitive as well since it's just got the one loop playing. You have a lot of sub sounds, and kicks, but I felt like the melody could have had a more dramatic presence.
Keep your chin up, and remember! Learning to produce takes time, and getting low scores and reviews is a part of the learning process.
If you have time, I would love to hear a review from you.
The most useful learning experiences come from people who hate your music with a reason, not from people who love it without one.
Hope this review reaches you, Goodluck!
3.5/5
PS: watch your downloads / subscribers to get a better feel for how successful each song is; 0 bombing used to be a bigger problem, but it still exists.
