This is a fan-made event for the Virtual YouTuber Hachi, to congrats her on reaching 100k subscribers on YouTube.
Hachi's original stream overlay is pretty simple and leaks his own signature. So it is important to insert various key elements in the design.
After the overlay is done, I was thinking it might be interesting to also do the loading and the transition too.
Then I went to try to learn After Effects, and with a few AE crash reports, the result is pretty good. (As a beginner…)
