would have started your second main cords at 24 not 31
also would have started your vocals at 33 not 41
i think that you would enjoy the results if you had the voice break down into a half second repeat...
through 41 up to a 1.26 you have the same girl singing, you can continue your buildup with simply adding the last 1/4 of your chopped audio clip to make it sound like shes kinda skipping the beat
at that point you could lead the song into a down turned beat at around 2.20 ish, then bring the girl back strong for a solo, followed with a duet of her and a really kickin audio, and finish it out with a soft bass line just like you did
keep working, you have a good half of a song already
