What is the quality issue in this picture that was refused, THANK YOU

1. Watermark and drawing errors

2. Strange texture in the potato, and oddly sized cross secrion

3. gibberish text on the calculator, poorly rendered numbers, and way too many rows of keys in the computer keyboard.

First image: There's a "for sale" watermark in the bottom left corner.

Third image: Some unreadable text on the blue pad and a few others on the top row of the number pad. Some of the numbers (1 through 6) have incorrect perspective.
