Nice work. Very atmospheric. The reverb makes it sound very dreamy. It's true what dem0lecule says, about the reverb, that if you use less reverb on the lead instruments the song becomes more transparent, but I'm not too much bothered with it. This way it sounds more like all of the instruments are in the same space, and I think it fits the mood of the song. It's very personal. Just try out different ways of using reverb for yourself, and do what you think sounds best. I look forward to hear more from you.
