An important thing to ask yourself when adding something to your design is: does this contribute to what I want to convey? Does this element help the viewer understand my character’s personality, does it suggest her background? If the answer is no, it may be better to leave it out. Think of what your character does every day; is her physique adapted to these tasks? If not, how does she compensate for it? Let the shapes you use tell the story you want to tell, rather than distract your audience from it.
