you may want to reduce the breast sizes a bit. generally what seems to be most attractive is around USA B to D cup or japan's C to F cup range.
at the current time of this comment the breast sizes are well into or maybe even past US H, japan J cup range. which is... gonna be hit or miss depending on the crowd. and considering this is a cest pregnancy game. your crowd is already gonna be limited. imo it's better to have the focus only those two niches and not bogged down by a third or more.
also you should consider posting your game to F95zone. just to help gain more fans and player base.
