Well
Right off the bat the guitar riff is awesome. The beginning vocals are a tad bit quiet and not as clear as they should be. As a matter of fact the audio quality really isn't that clear either, but it's not like I expect you to have a producer or anything...
The song has potential I'd say, it just needs to be produced. Like I said, the beginning guitar riff is pure gold, and the lyrics don't seem too cheesy either, they seem alright. You seem to have a good singing voice too, I just don't think this recording does justice at all.
When you get to the chorus I wouldn't strum the guitar harder either, just seems kinda pointlessly dramatic for a chill song like this. I do like the song name though, hybrid rainbow totally sounds catchy. Hopefully some of this feedback helps you. Keep up the good work.
