Flyer design rejected need feedback

I dont understand why that is gonna rejected.

The message is that it does not meet the minimum technical quality requirements please give a feedback to improve it thankyou!

- Work on Text Styles

- I’d work on making the bottom look much better than regular gradient, with % to cover.

- Text is nice actually (main headline) but could be hard to read. remove some of the sparks from it…

- Overall design is too bright…top part especially

- IDK if you added the shine effect, later to make it look like that for preview..or it is the final file…but it doesn’t seem nice…get rid of it.

- Add some more things to the background…too empty

- Good Luck.

Improve upon the center heading text. It needs to be clear and readable; currently it’s neither.

I would also reduce the gloss effect on the text, and increase the contrast as a whole.

You may also want to add an additional center element to the design; it currently looks a slightly empty.
