can some one have a look and tell whats wrong with pencil sketch, it is AI generated to description to a specific scene

This is generated to a scene to illustrate a small-town day to day activity. it is rejected.

This image was generated with AI (declared as Generative AI at upload) and submitted under the Illustrations category. The title clearly states it is a pencil sketch/graphite illustration. It was rejected for quality issues.

I cannot identify what the specific quality problem is. The image is 3072x2048px, well above the minimum resolution requirement. The pencil sketch style is intentional cross-hatching, monochrome linework, and stone texture are deliberate aesthetic choices, not artifacts or noise.

My questions for the community:

1. Does Adobe Stock's automated review system flag intentional pencil sketch texture as "artifacts or noise"? Is this a known issue for this style category?
2. Is there a minimum contrast or clarity standard that monochrome sketch illustrations need to meet that differs from color images?
3. Should pencil sketch AI illustrations be submitted differently different category, different file format, different resolution setting?
4. Has anyone successfully submitted AI generated pencil sketch or charcoal style illustrations to Adobe Stock? What did you do differently?

Any feedback on what the reviewer likely flagged would be genuinely helpful.
