I have just finished watching all of the 12 TD episodes that are out so far and I can just say that I am in love with this series. The artstyle plus the narration you give create a perfect match, making these short films a treat to watch. Being a college student myself (Industrial Engineering) I can tell that most of these animations can be applied not only to those studying in art school, but to all careers.
Anyways, as I said artstyle is great, storytelling was awesome, and the several sound effects gave it a great touch to it. I, personally, believe that your Technical Dave series need no improvement so far and are perfect as they currently are.
You have gained a new follower that will definitely be waiting to see what topic you illustrate next on the series.
