Hi guys. My flyer template is rejected and I don’t know why. Please help with some advice. Thank you

This Calendar was rejected. I don’t understand where I did a mistake. Somebody advise. It takes ages to design such yet we get hard rejections without clear explanations. To make it more frustrating we’re told not to re-submit again. Issue “quality standard required”.

The design looks oudated. There are similar free files out there.
