i believe you may want to focus more on the five rather than the piano
Well how similar is it to the other flyer? It would be soft rejected I’m sure anyway, you really need to improve the typography. I would put the word “years” somewhere over the top of the 5, lower than where it is now. Where it is now just looks like it’s stuck there with no thought, it’s not integrated in the design. The lower section with the plain background looks bad, you should change that.
I hope that helps.
and that’s not how you spell London
