amazing sound design - sharing with you an idea for the sitar in the intro: if you automate a progressive level increase the transition would be smoother and by the same occasion you directly inform the listener about the mix's depth. also, its pulsar delay could be automated as well from nearly mono to full stereo, it would give a great 'opening' feeling
with pleasure :) regarding the progressive volume increase, an idea worth trying is to progressively increase the wetness of the pulsar along the volume increase of the sitar synth, then to compare with how the opening would sound if you keep a steady wetness like it is currently
