Heavy Light
This reminds me of the many jam sessions I had way back, when we just wanted to make music, no preconcieved pretentious conceptual bs, just fun and all about the moment.
You might want to push your playing style for all it's worth, listen to primus, sonic youth, pavement etc. Don't be too shy with the guitar, it's the main element and it's a little too reserved imo. Just adding a little chorus will fatten it up. It would also be cool to have a slight change in the dynamics in the chorus/break.
The guitar is ever so slightly out of tune, I don't know if this is on purpose or not, but it gives it a raw charm that I think works well with the song. Just work on the tone, even do some more overdubs to reinforce the riff.
Good Work!
