good song, video needs work
you have good taste in music.. I can give you that much.
the video itself is a bit weak, unfortunately. good effort, good start, but it kinda pooped out in the finishing, I guess.
one problem is that the actions follow the lyrics LITERALLY. that can get redundant.
for example, instead of showing a literal heart during the "my shallow heart's the only thing that's beating" line, maybe you could, instead, show a vein pulsing in the stick figure's neck, arm, leg, or whatever.
if you can improve on the animation and make the actions a little bit less literal to the lyrics, then I think you'll get better reviews overall.
to sum up, the general idea is pretty sweet, it just needs work. good start.
