Damn, you pulled this off real nice. The graphical quality is astounding - far beyond a lot of anime that's published under big companies, though the animation was a little less consistent (this is fairly common for this style of animation, though.)
The facial expressions and music were obnoxiously cliche, too. I understand that was most likely what you were going for, as is the case for animations like Chuck's New Tux, but it really was over the top and just cringy. Believe it or not, I was rooting for the girl to die from the moment Cupid appeared. By the time I saw the steel tips of the arrows I could already tell something was a little off.
If you were just going for something totally absurdist, it might have been kind of funny to have the girl puking up blood and just cranking up the gore factor in general. The animation already relies on over-the-top cinematics to enforce the cliche, so you might as well have taken it a notch further.
