Beginning piano could of used some complexity (maybe some velocity variation as well), and I find most of the sound leans to the left ear too much, making it unbalanced. The flute sounds that come in is quite good. Overall, you did fit the bill of the them you were given, so good job.

Coloring style, hair, lighting and style of the vagina is very good. Much like vintage anime.

I actually love slime hair, I have a girl with one too. Though her hair is a little less viscous than this. Very cute and drippy!

Probably one of my favorite images. The butt squish, her face, angle, softness, blush all of it is so well done.
