I noticed that the animation is of a good (not superb, but whatever) quality.
And the writing is usually really good as well.
So why the low scores? 3.47 is not the collective score of the rest of these parts.
The final remaining piece is sound, in this case I want to emphasize voice acting. You probably enjoy doing the voice acting, if you want to continue that's up to you, but to take these animations to the 'next level' I think you need to start trolling the AP for some voice actors who are willing to help you out.
I enjoyed all the jokes I just feel they could have been told better, especially the 'now what' line. That caught my attention. It should've been a laugh, but it wasn't.
