Good feel
Still needs a bit of variety. One thing you do well is match sounds to create a feeling (at least in this song), but I think it would pay to focus on the technical side of your music.
For example, in most of your songs you use a very 'safe' four beat canon, and repeat it continuously for the entire song. About the only time you did anything different in this song was at 0:42 where you introduced a short break. This worked wonderfully, but I think it's only a start.
At the moment I don't think there is ENOUGH in your songs:
I would encourage you to experiment with lots of different elements to add variety.
- Maybe add a longer, winding melody over the four-beats. Most really good songs have AT LEAST two melodies going on.
- Or try merging two of your songs (ones that match, obviously) and play the two songs in and around each other - maybe harmonies...?
- Try sampling audio, and adding that - like you would lyrics - and see how you like the process (youtube.com/watch?v=A2yt1ooLQGo) I'm guessing you wouldn't add lyrics, so this is a possible compromise?
An even better way to get a grip on how variety is achieved, is LISTEN TO SONGS THAT ARE SIMILAR, and write out exactly what happens in them. Divide them up into segments. What do they do to keep the song interesting?
Learn to recognise elements like Intro, Verse, Pre-Chorus, Chorus, Bridge, Collision, Solo, Outro and Break (this requires some study on your part).
For example, that Pixar remix I linked to earlier may have sounded like a mess, but it was VERY CAREFULLY CONSTRUCTED:
Intro (Establishing tone)
Verse 1
Verse 1 (With increased beat)
Verse 2
A little break
Verse 1 again
Verse 2 again
Very different Verse 3 (Without backing)
Very different Verse 3
All three verses fitting together perfectly (The best bit)
You see how, even if you don't like that type of music, there is no opportunity to be bored? It all sounds fresh and new, while still being the same song.
Whereas your song would read something like this:
Short intro (Subtle main theme)
Main Theme
Break (Subtle main theme)
Main Theme (With string backing)
Main Theme
Main Theme
Main Theme
Main Theme (With string backing)
Main Theme
Okay, I didn't write it perfectly accurate, but you get the idea. I could have turned it off after about 30 seconds and still have listened to everything.
Once you've listened to songs that are similar to what you make, start listening to songs that AREN'T similar.
The best action-movie directors take notes from dramas and comedies, the best digital artists take notes from classical painters, and the best musicians listen to all genres.
Also, at 1:45 the string-like backing sound is off tune, and sounds grating. This happens a couple of times. You have to be careful, backing sounds must be perfectly matched.
Anyway, this song has a lot of potential. I'd love to see some more things done to it.
