Artists are never labeling their work as "sketch" to be falsely modest! and what each artist considers sketch/ doodle level varies per person.

Sometimes offer a free piece of art called a “Bad Doodle”. Most of the time these come out semi polished. Sometimes they don’t. The whole point is for me to create without promises of quality or accuracy. I’ve been chastised for “mislabeling” the good ones. -_-
