I’m glad that the video title includes the series title and episode number. I recommend also adding the episode title.
Also, the title sequence is an entertaining mini music video, but if you plan to have many short episodes, a 41-second title sequence may be too much. Maybe starting with the fourth episode, have a five-second title sequence.
The very popular Carmilla web series illustrates these points: Carmilla - The Series | S1 E1 "Disorientation" - YouTube
