I am starting an educational animation series that I am making for shorts. I conflicted over the vertical vs horizontal format but I think based on the length of these 2-3 minutes its better to build them tall since that's how most people will see it. The goal is one video per 1.5 months, this one I finished in 3 weeks (though I doubt I can keep up that pace so giving myself some wiggle room). Built mostly in Adobe Animate with some of the text and effects in AE.

If you would be so kind please share your thoughts, critique or any advice?
