This review is going to have two parts.
A: In regards to your comment on larrynachos review, it's totally fine to go with something that sounds good. That's how all my songs are. It's not a bad style to develop, because i'll tell you, I imagine planning a song would be much easier, but I feel more creative going from bar to bar not knowing what i'm going to come up with next. Makes it interesting and I'm usually pretty stoked about how things turn out when I just play it by ear as you described.
B: At first I was pretty stoked about where this was going. Had a simple but defined intro. When I realized that it was mostly just one or two channels, I was a little disappointed. Once the beeps came into play, I was pretty confused. Overall, i'd say really work on creative some distinct and catchy melodies and harmonies to go with your ideas. Even if you use a really minor scale, you can make anything sound epic if you do the right stuff with it.
Good luck!
