The distorted lead was used from about a quarter of the way through the song to the end, and it got a bit obnoxious. Sorry, I wrote that a bit awkwardly, I guess I wasn't paying close enough attention. When I said too loud for its surroundings, I meant it was mixed too loudly compared to the other instruments. It should be easy enough to edit that, just turn down the volume on the track. I just mean a section with a different feel when I say contrasting sections. I'm not saying completely change emotions, but maybe back off on the intensity temporarily, or something along those lines.
For the ending, I'm saying right now it ends on a note that just sounds a bit random, and doesn't really loop well at all. But the way you end should be up to your own discretion, you composed this piece, not me.
Being picky about your own work is good though. It shows that you actually want to grow as a composer.
I hope I was more articulate in my points this time. I'm a bit out of it tonight, I guess.
