Rejection of imagen for quality

In the first image, the highlights are disturbing. You need even lightning for such assets. It's a nice try, but I think, the picture does not work because the right and the left side are too different, and neither of them can be used correctly as a texture for something.

The coffee cup has exposure problems as pointed out and as you see in the histogram:

Besides having blacks missing, you would also need to lighten the shadows. As you see with Nancy, there are different ways to achieve that, I would do most of the work in Lightroom/Camera Raw given that I would have access to my raw files.

In addition, I would try to get rid of the small stains and imperfections of the background.

You do not have crema on your coffee, that's a visual defect, making your asset less attractive.
