Vague but has potential
I could imagine literally hundreds of ways in which you could expand on this, so it's really going to come down to your own intent with the song. Adding backing melodies/chords would certainly give you a better idea of the mood, because right now it feels a bit "naked". I get the sense that it is supposed to sound urgent, like an epic fight scene. Percussion wise, I could imagine some fast breakbeats or a slow, heavy bass and snare pattern. These are just my suggestions.
thanks. The reason it feels naked, is because it is using the default tone. It sound like a telephone tone. I will probably add breakbeat.
