First off, things I liked:
: Sound design is good in that it doesn't sound like a 2008s song.
: Melodic ideas aren't bad, especially the riff at 0:28.
: You have a good sense of bass. I heard a lot of low end, something a lot of songs lack.
Next, things I feel could have been better:
: Your song is pretty quiet. For something like this, I feel a bit more could have been achieved.
: I felt the buildup at 1:00 was cool, but the part directly after it didn't do justice to all the tension built in that moment. This is partly because your sound is so quiet.
: This song could have benefited from slightly better instrumentation. I felt some sounds in here didn't quite do the melodic ideas justice. For example, I felt the chord pluck sound in the beginning could have been shorter and more staccato
: More interesting things could have happened in this song. The first thing that comes to mind is the use of stereo, in that there was none. Panning is a great way to give your sound more depth.
: Ultimately the sound gets dull after a while. Even after the first listen, the sounds quickly become uninteresting. This is probably a combination of all of the factors above, plus the fact that you repeated the same thing a lot.
I guess there are some pointers for you. Keep composing!
Thank you so much for your detailed response! I'll look out for these things the next time I make a song, and I appreciate this so much.
