I'd like to suggest more Cartoon Animator 4 characters, face parts (i.e., mouth, nose, eyes, etc.) and wardrobe in the style of the 4 included characters - Martha, Phillip, Red and Roger.
The Social Buddies pack characters are more cartoony and seem to include the single arm (rather than Upper Arm and Forearm) characters. At this point, I am spending hours creating my own characters. I'd like the option to use Reallusion pre-made pieces (like CTA2+ characters).
I'd also like to see more practical motion packs for CTA4 characters - realistic walks for F characters, typing, etc.
