Lilith is absolutely adorable. Great that you where able to pack so much personality in a non-speaking character. (Some people are unable to do half as much with a speaking character).
Speaking of personality I think you did well setting up the personality of all characters so far. While we don't get a long expose for each character (thank god
) it is clear what their base is and that you have a good idea of what they will or won't do.
I would dial down the naivety of Emily just a little though. Even if she is neuro-divergent and a little blue she still has urges (unless you are going for asexual) and with a mom that writes romance novels she will know the basics of the birds and bees. (It shows that her mom is relatively relaxed about sex and there is no telling what a curious teenager will do when everybody else is asleep or not at home). So I'd keep the socially awkwardness but lose the almost asexuality in her character. (It's a fine line I think.)
Other than that great art. Renders are done well and the girls are cute and distinct. The models look quite natural. I would have preferred a wider range of chest sizes but that is personal preference.
The story so far is promising. A setting you can do a lot with. It seems well grounded as in all characters are accepting of the world they live in and don't do stupid things as if it is the first day in that world.
Quite interested in what is coming next.
