It sounds quite well done. My daughter loves this song. Is this you singing? It sounds really close to the original. I think the guitars in the chorus are currently burying everything else though. They could come down some and if you want to maintain the sense of power when they come in, try automating a dB or two boost in the bass there, or if the panning of the guitars is the same in the chorus as it is in the verse, try changing that up some as well. I was expecting some pretty hard core riffage to assault my senses, but instead I am greeted by a stadium rock power ballad! The mix sounds good. Is that all Line 6 sounds on the guitars?
