I've made a video of about 1 minute so far. Just 4 more minutes to go! I want to make it more efficient, but doing so would compromise the quality. It's been a cycle of creating, adjusting, fixing, and readjusting.
However, considering it's my first attempt at motion, it's gradually becoming satisfactory in terms of movement. Especially the fly and the movement of her mouth and tongue are naturally done well. It's not just a typical up and down motion like in common videos.
