Rejection for Phone Mockup

I uploaded a phone mockup that can be used by designers to put their screens on. It is a minimal mockup that supports 16:9 ratio. It is a sketch file in which one can replace the mask with their own screen. I was wondering why it was rejected. It was rejected on the grounds of quality and no resubmission is allowed. Any help would be appreciated.

There’s are SO many device mock templates for sale already here in different formats and also available for free online that you need to bro g something super valuable to be approved eg various perspectives, views etc

Hey, thanks for your reply.
I didn’t come across much mockups on Sketch and also most of them were trying to be photorealistic and thus posted. Anyway, this was my first post and I will keep in mind the points you mentioned for further posts.
