Hi @PiergiorgioConte , there appears to be a consistent noise / grain issue in all of your photos and no sharp focus. Are you adding a filter to try and make it look like older film photography? If you are adding a filter, Adobe Stock will keep rejecting your images. Take a look at your images at 100% magnification.
The cropping of the maniglia photo seems odd with the white background on left and right. It almost looks like a border that needs to be cropped out.
Remember what Adobe Stock wants:
Businesses, ad agencies, design studios, and marketers want to buy great-looking, distinctive stock photos and illustrations. For your images to have commercial value, they shouldn’t show noise or dust and they should be well-composed, appropriately lit and exposed, and processed in an inconspicuous way.
If you are new to stock photography, here are some resources that might be helpful.
I hope this helps. Best of luck in your future submissions.
