I mean, the frames where you see the inside can still be long, those are fine, just the ones where it transitions from outside to inside I would speed up. But yes, animation takes a lot of time!

   You are right, this work has only 13 frames. Because I don't want a complete loop to be too short, I lengthened the time of each frame. I should add more frames, but this may increase a lot of work, so I gave up.

I like her little home, very nice! But the transition animation seems a bit slow?
