Hard rejected flyer. How can I improve?

Hello, I recently submitted a 5K Run Event Flyer and it was rejected. I made sure to organize everything and the design doesn’t seem bad to me. But I would like your opinion, how can I improve it?

That sneaker doesn’t fit, try with something else, maybe some more elements instead of it, the rest looks nice, nice colors.

Thanks for the feedback. I’ll do my best to improve it :slight_smile:

As @Kipet said the sneaker is not good.
And also in my opinion the design is something very basic… I didn’t mean it’s bad I just wanna say it has only few elements try making it more interesting and unique… All the best…:+1::+1::+1:
