My work Blurred background rejecte, why?

My work Blured background was rejected last week, I don’t understand the reason, can anyone help me why this happened? How can I improve my work?

I once (in 2013) uploaded a similar set to GraphicRiver and it was rejected as well.

“In order for submissions to be considered for sale they must be of high aesthetic and technical quality, unique to our library.”

I was a bit sad at first but had to accept that blurry backgrounds aren’t really a unique item and of a very high technical level. So I moved on, open sourced my sunset package, and made sure all my future items were top notch.

Thanks @pqina
