Adding some blinking and mouth moving would add so much life to the characters dialogue and interactions!
Bath sprites: A good idea! I'll be adding that as soon as I have time for it, as well as the underwear sprites you mentioned.
scrolling pictures: I'm glad you mentioned this again! I seem to have forgotten that this existed. Originally, Yikshi's dreamscape was supposed to be a full body in which you could scroll, but I couldn't find anything to make it so. If I can work my way around with it, I might even still update Yikshi's screamscape, since I was never really happy with how it turned out!
Blinking and mouth animations: I agree, it's a nice addition. I'm working on learning how to use Live2d at the moment as well. I found a plugin that lets you implement Live2d models into MV, so if I'll ever be good enough at it, you'll actually see more than just blinking and mouth animations!
