The moderator returned a reason to you. It was probably “technical issues”. You should forward that to us.
Your picture is noisy, and your cutout work is erroneous:
You will need to submit artefact free pictures. When using Photoshop to edit, the picture should look like unedited. Look at 100% and 200% at your pictures. If you see anything like noise and particles, artefacts etc, that needs to be addressed.

In addition to the flawed cutout edges pointed out by Abambo, there are small spots all over the background.
Myślę, że kolejnym punktem do rozważenia jest twoje pochodzenie. Myślę, że to nie jest dobry kolor do pizzy. Żółte tło nadało zdjęciu ogólny odcień żółtego, dlatego balans kolorów jest nieprawidłowy.
