Old style design approach, in addition to what @DesignSomething said.
This reminds me 2015s
as @DesignSomething and @ki-themes said its not pro and modern design, Its out dated, I would suggest you go through the acceptance guidelines, Make sure your design is original, follows modern trends in design, and has a creative twist to it. Pay special attention to the color palette, typography, and layout of the flyer. Try to experiment with different colors, shades, and hues until you find the perfect combination that adds appeal to your design. Good luck! I will wait for your next submission
Thank you for your response.
I don’t see anything wrong with it…I like it. Nice work!
