Good luck.

I agree with ​@Nancy OShea. The spoon should be in the cup and the flower isn’t really necessary.

Your image contains three randomly placed items that have no relationship to each other— in style or composition. They’re just floating in space. The spoon looks realistic but the other items do not. The picture as a whole makes no sense.

For comparison, this what you’re competing with in these keywords.

Hope that helps.

La calidad de una imagen no es solo nitidez, la composición, el contexto de la imagen, que comunica,  que tan comercial es la foto. eso son aspectos a tomar en cuenta. 

The edge finishing is sloppy.
