Is drawing only the eye and eyebrow, or drawing the head from the side with full features except for the eye, considered an imitation of Allah's creation or does it fall under prohibition?

What you mentioned about drawing an incomplete image of a person, such as drawing an eye with only an eyebrow, or drawing a head from the side with hair, an ear, a mouth, and a nose, is not forbidden and is not considered imitating Allah’s creation.
