Good ethereal song. Very "Jethro Tull"ish. Some of the synth parts in the beginning of the song are masking the vocals, but are ok at 2:30 on. The intermittent lead vocal double is a cool idea, but imo, should not be panned hard L/R. Either keep both in the center, or 3 vocals - strong C, light L/R.
Also, the lead vocal drop in volume at the end, is that making room for the lead guitar?
Good tune.
