Hello!
Firstly I would really start of by even out the volume of the intrumentals and the vocals. Right now you are soaring way over the track. I like the idea of double tracking vocals. But to make it sound even smoother, you should choose one to have as a main track and it will sound more full. I am also a big listener to the modern age psychedelic rock, and if you are looking for that sound, I say, add some layered synths in the mix!
I like the "Being for the benefit for Mr. Kite"-theme (or carnival, I suppose it's the same thing really). You could really make something more out of this track!
