Motivos de rechazo por mala calidad

De todos modos,me plantearé seguir subiendo fotos aquí porque tanta,tanta perfección me abruma,sobretodo,teniendo en cuenta que en otros sitios me las han aceptado.Pero bueno,seguir mejorando nunca va mal.

If you check your histogram, you will see that exposure is a problem:

I am also uncertain whether the extremely narrow depth of field renders this asset functional. My third critical point is the cropping. I think that you should have included some more “white” (green?) space in all directions.

Hello,

The white balance needs to be changed a bit in both images. The background is green, so this gives a green colour cast to the image. Try to reduce the green tone a bit by adding some magenta and increase the temperature - add some yellow.

E.g.

Try to bring out the colour of the flower a bit more.

I don't think focus is an issue.

Quality includes colour temperature -white balance.

I believe it's a compositional issue. There are millions of flower images on Adobe Stock and you need to provide something really unique to get flower images accepted.
