The portrait system will show weight gain & I've split it into two components: the face itself & the shoulder area, which will change size at different rates depending on the gain pattern.
To help make the portraits more diverse, I've also added more hairstyles, hair colours, eye colours and skin tones. Eye shape is linked to personality, and many of the facial features will also appear in the portrait. Finally, I've added two new customisation slots: eyewear and piercings. You can visit new locations in town to change these & they'll also be linked to personality. For example, a Rebel will be more likely to have piercings, whilst a Bookish girl will be more likely to have eyewear.
