Hey good work. You've come along way already from your first demos! For the most part it does sound pretty awesome.
Upon listening to the track posted and your newest song, I've tried to think objectively and brainstorm on what your music could benefit from.
So far it seems like your tracks could use:
More WAV work.
More instruments.
More emphasis on tracking in general.
More well-defined hooks and less recurring melody lines.
More emphasis on songwriting in general, for example the A part, B part, Bridge, etc, should be moderately distinct and at least one should be immediately memorable. I'm not saying you have to write obnoxious earworms here, but something that steps forward in the song and takes you somewhere is always desirable.
More focus on tracking volume. (Dynamics are very important in tracker music. Try to write as if you are mastering as you go, so after recording you hardly need to make any changes at all. It took me a long time to figure this one out. I still struggle with it when it comes to WAV sounds.)
Less emphasis on DAW effects/post-production.
- Opinion time, feel free to ignore the following. -
This mix is loud, flat and muddy for my taste. (I prefer clean gameboy sounds most of the time, so take that specifically with a grain of salt.)
Remember that the gameboy as an instrument is interesting because even when it doesn't sound like a gameboy, it still pretty much sounds like a gameboy. Use this to your advantage, don't try to cover it up. I'm not trying to sass you here, but to me it sounds like what you want to be making is more mainstream EDM type music with chiptune elements. If you want to make music that sounds more like professional electronic music, there's a wide range of trackers and daws out there that might be a better fit. FL studio is a great middle ground, I'm told. Finding a footing stylistically can be a serious challenge, don't be afraid to experiment. Find what feels good and all will develop into what it should be with time.
