Failure? that makes me feel weird then to say that this is one of your best. Please don't stop doing songs like this. The chiptunes are super cool, however for me this is where it's at. Love the classical ellements, the the high energy overlaying the calm sad tones.
I know what you mean with something not sounding how you envisioned it. However keep striving for the masterpieces in your head, espeicaly if your failed attempts sound this gorgeous. I can't even imagine the awesomeness of you suceeding. I hope you continue to work towards that. =)
