My Item ''10 Promotion Instagram Banners" hard rejected, need some advice and feedback.

I have a few questions about my item design that got rejected.
What did I do wrong?
How can I change it to be accepted?
What’s your opinion about it?

well as for me, i think this is nice indeed … this is working in all environment in my view, apart from maybe reworking a bit the typo, i do not see what could be done …
