There is a fundamental difference between consistency and "body of work."
This is what I came here to say, but Katy said it way better than I could have.
I think when people stress out about not having a "style" they should just let it develop organically instead of putting themselves into a box. There are lots of artists that refuse to be limited by one style.
I think an artist would do well by continuing to push themselves in different areas as opposed to trying to make everything they do feel the same.
