Technical Problems?

It's somewhat random in my opinion. They told us that we should not be offended when our images get rejected. I just live with the fact that 50% of my images get rejected for whatever reason.

love your images.

I like the first one best.  But overall the lighting is uneven.  And there is a glint of extreme light on the knife guard that needs attention.  Keep working at it.  

Photo 1: some fringing arround the chili can be seen at 250%. Overexposed highlights. IP issue with the knife. Bad cropping.

Photo 2. Focus. Underexposed. Overexposed highlights.

Are these the original photos you submitted to Adobe Stock?  I only ask because they seem small.  If they aren't the originals, could you please post them.  It is easier to give a true critique based on the originally submitted photos.

On a quick look, the peppers on the cutting board seem noisy and underexposed.  I would suggest you would do better with a slower shutter speed and a lower ISO than 1000 to reduce the noise.

I would think the other photo with the knife is also somewhat underexposed.  On a side note, you may have an IP (Intellectual Property) issue with the manufacturer's name on the knife blade.  It would be best to clone that out.

I hope this helps, but again if these aren't the original sized submitted photos, please post those for a better critique.

Tal vez no les gustó la composición, o consideran que las sombras no son adecuadas, personalmente  creo que por motivos personales y no tecnicos, pero no hagas mucho caso de mi opinion no soy experto
