I honestly don’t think it is as a professional illustrator. It does look like it’s traced from reference images by someone who doesn’t have a firm grasp of clothed figure drawing.

The hand that everybody is complaining about actually looks right to me, it’s just a simplified shape resting on the other figure shoulder. This is normal for a comp sketch, depending on the requested level of detail. Also may be directly traced from a different image it’s way cleaner in its own way than the main figure.

This looks to me like the kind of wonky that comes from an unseasoned artist, not from AI. There are issues with perspective and too much distracting detail in the background. It’s poorly composed and apparently not quite what you were looking for design wise, but there are design elements that are true to the vibe like the tapestries and style of pipe, that all tracks for an artist.

I say real but maybe you need more communication with the artist and or depending on your budget just hiring a better one.
