By "doing" I hope you mean "releasing" and not "composing". Keep composing tunes, keep racking up experience, especially if you're doing it on a portable gameboy instead of an emulator. Of course, everybody needs a break. But if you get an idea and have your gameboy read, track it down, man.
Here's a fun interim project: Try transcribing your vocals into the gameboy (given your style, the wave or noise channel [lol] would probably be best for that, but who knows? You may be able to grapple some screams and screeches and growls out of the pulse channels. ). Do it without the intention of creating a releasable song, but just to experiment with sounds and analyze your vocals in a more "musical" context. Who knows, you may GET a releasable song out of it =P
I just noticed something. Your tracks are very heavy on the high treble frequencies. Try dropping in some bass to balance it out. It also seems like you don't do much polyphony (multiple melodies) with your tracks, which isn't really a great thing. At least use power chords. Seems like you tend to stick to one melodic instrument at a time, (echoes don't count as multiple instruments). I still like the contrast between the boops and the screams, but it needs more in the way of melodic and harmonic content. Even a Round of "Row Row Row Your Boat" style echoes (you know what I'm talking about, right?) would work.
Also... each new post certainly does bring a more fleshed out feeling, but they're all starting to sound the same. Especially the screaming. I keep hearing the same "stay away from meee" rhythm (I know one of them was a remix, but still...). And, as opposed to heeding the advice of people saying to get more "guttural" and "deep", it seems like your screams are becoming more and more harsh, lol. But, hey. At least it's true to form: a kid angsting his heart out about stuff that he doesn't like. lol
Wow... I didn't expect to come back and post all that. My hands were washed. Now they have been soiled again.
