Until 0:40 the drawings were good, but it looked too much like cut out animation. You can improve that e.g. by increasing the size of the character at 0:12 as she moves towards the camera. This would give a more 3D feeling.
The voice over had too much pathos for my taste.
But after 0:40 the animation is top notch: Well drawn lights and shadow, good timing and fluid animation. Keep that up! Some professional studios produce worse stuff than that.
