Not overly sure how the anatomy and placement is working out here. Kinda seems like a abdomen vulva. And going with prior work from them, they could go with tinkering up on their female anatomy. Especially to match their male. Placements seemed to be rather correct on their other drawings though.

They got an overall neat style, but can need work on their proportions, angles, anatomy and placements. But it looks quite promising. They do good expressions imo.
