rejected with the reason "Similar content in our collection."

Hello everyone,

I'm new to selling on Adobe Stock and was hoping to get some guidance. I recently submitted a character set that I created myself, but it was rejected with the reason "Similar content in our collection."

I've spent a lot of time searching the Adobe Stock library, and I honestly can't find any assets that seem directly similar to mine. This has left me a bit confused, as I'm not sure what the reviewer saw.

I'd be very grateful if you could help me understand a few things:

How exactly does the "Similar content" rejection process work? Does it flag things based on visual style, concept, composition, or something else?

Is there a way for a contributor to see which specific images or sets might have triggered this rejection? I'm struggling to figure out what to change if I don't know what's considered "similar."

What's the best way to approach this? Should I modify the set and resubmit, or is this a sign that the overall concept is too common?

Any advice on how to navigate this as a new contributor would be incredibly helpful. Thanks so much in advance for your insights!
