I love the A section!
Hey ther, LOVE the A sections! Your B section doesn't need the other synth line that comes in, it sounds like its fighting the one that is already there. Also, add a drum part to the B as well. Your C section is cool, but a LOT longer than the other sections. Try to cut the second half of it off and see if you still like it. I think it will be amazing when it's finished, good luck!
