Very Enjoyable
Your cartoons always had a quality presentation when it comes to the character design and backgrounds, and this showcases some of your best yet. The fact that you got this done in a few weeks is impressive to me.
Another thing I liked was how ominous it felt throughout; you did an excellent job with setting the darkness just right and the angles of the shots helped this case out as well. Voicing was clear and acted out well also.
So yeah not much else to say other than I liked it very much. I haven't really seen any prime candidates yet for the flash-off so you're definitely on my list.
