if this is considered low quality then each and every illustration by this artist should be deleted. literally has the same quality that this artist has already accustomed us to, Hell, it's even animated, you know that animating requires more effort than a simple static drawing? also, the animation is fluid, no robotic animations or animations with too few frames. "but it looks like it was made in MS paint" let's criticize more the quality of the drawing than the software used, maybe the drawing is not very anime style, but if we justify it as something similar to a chibi, it is quite decent, anatomy within that parameter is fine.
want to see a real bad drawing made in paint? check this out post #5294126 bad anatomy, bad use of shadows, weird faces and a bad imitation of another artistic style/parody.
