These are great! Only issue is that the sprites for Sarah, Lisa, and Mrs. Taylor are all found within the female-characters.png file instead of the two separate files you have listen in your post and I'm not very knowledgeable when it comes to sprites, so I'm clueless when it comes to editing the female-characters.png to incorporate your revamped sprites.
Other than that, really happy with how they look and I've added the compatible ones to my copy of the game. Would love to see some of the unique sprites such as $!MomShower.png (which uses the original sprite) modified to use your revamped sprite.
With the additional sprites added from the other busts, they wouldn't fit in the same file.
To be clear, these are not drop-in ready, they're more like raw resources. If you added them in now and overwrote the old files with them then the sprites would probably look weird, or be at the very least out of sync, while some characters wouldn't appear correctly at all.
In order for them to be used, they will need to be setup from the game editor.
I could probably make some drop-in ready versions if people want them, but it would only include sprites that are already in game, so the additional sprites from the other busts wouldn't be included.
