Problems with quality

I cannot understand why the photos were rejected. Help me who can so that I don't make the same mistakes again. Thank you.

Most likely a focus problem.

Thank you for your response. I'll try to cover the aperture more

In the first image the depth of field is too shallow, rendering most of the subject out of focus. It also seems overexposed.
Depth of field is also too shallow in the second image, and you've cut off part of the subject on the left edge.
