Covid-19 Coronavirus Medical Flyer(Item hard rejected. Please Help.)

Hi!
I am new in graphicriver and recently I have started to upload flyers, but my first 2 flyers got hard reject.
I have tried to find out my fault but couldn’t so I will be very grateful if you guys give me your valuable feedback

Previews of rejected items:

hi the problem is that your item is basically lacking finesse, the global style is too raw, most of the elements are too big and there is a negative impact on the way the item looks and on the global harmony. In addition, colors are not always very much in keeping with usual theme colors and some combinations are definitely not super making sense indeed. I also recommend the u try to introduce a bit more originality in the lay out , the shapes and the picture u are using so that this looks more unique and more worked out too
