7 1/2 min????
This song goes on entirely too long, boring synths, and a crashing waves loop, and inferior, repetitive, homogenous drums. Kind of overindulgent, cheesy melody. Nothing really has any power in this song, I'm kind of waiting for the breakdown, or a second verse, or a chorus, or bridge, or... hell, anything. Also, it's not really very ambient, the drums and the melodies and key imply action. Not much really soothing about this piece.
Sorry if this all sounds harsh. It seems to me like you worked on this for about 2 hours and called it a day.
