Observations:
- Synths emulate the retro aesthetic of the game.
- I would have the drums be more prominent in the mix. The song is missing quite a lot of energy from their week presence.
- The guitar sounds a bit thin and sticks out of the mix.
Recommendations:
- Listen to a song in the same genre closest to what you aim to achieve and think about how they mix there stems. Ask your self, how loud is the guitar compared to the drums, synths, etc.
- The guitar sticks out partially because it's the only non artificial voice. To make it more at home, add other elements like it (i.e. real drums instead of electronic ones) or nix the regular guitar and use an artificial (samplers/soundfonts) or generate a voice to fill the role. (synths, vsts, etc). Hard committing to either will help the elements feel more cohesive.
- Another observation is that this feels like you're just riffing on this back track. Nothing wrong with it, but if you want it to feel organized and intentional, I would start making discrete sections that represent a specific melodic idea.
A melodic idea can be something as simple as an "antecedent consequent" phrase.
These ideas can become the building blocks of your song that provided hooks for people to attach too.
And when you repeat a section, that communicates intentionality.
As Adam Neeley says, repetition legitimizes. repetition legitimizes. repetition legitimizes.
