Noise, lack of contrast and composition. Back up and get more of the subject in the frame and omit the foot.

Your asset has a high noise level:

In addition, it is not very sharp. This could be a consequence of the noise.

Noise is also the refusal reason for the toilet brush:

The image is also not sharp, and the composition is not great with that part of a foot in the image.

I think the disturbing background needs to be replaced and the colors are alittle drab.
