athh these rejected due to ' quality issues' can someone explain?

As someone who submits only AI, I've circled almost everything I would have fixed or eliminated prior to submission. And be aware that even a single error or poor rendering can result in a refusal.

View your images at 100% to 200% and look for issues like these. Also, these are quite similar to one another. You should limit similar content to a maximum of three assets to avoid similar content rejections.
