Well, first of all, I like your tone, but as a whole, it lacks something. Bands like Sunno))) do 20 minute songs, but they work with vocals to keep it interesting. Maybe do something with effects and your voice?
Second, I like the distortion, but there's not enough delay on the bass, so the bass doesn't start droning, it just stops at a certain point. When your bass really drones, you can start working with layers, adding different sounds etc.
Nevertheless, keep us posted
