Apart from very similar, the artwork itself ( I’m sorry to say this) its very low quality. You should check out the quality of the other flyers that are selling out there and compare it with yours. And then ask to yourself: which one would you rather buy, a high res sexy flyer or yours. I’m sorry if I sound too harsh, but that is my opinion.
Hello, You need to work on your fonts … give them some style! Keep the Masks … but delete the eyes from the middle one …. The speakers (for me) are toooo large … The details at the bottom need WORK!!! check out some other flyers and see how the do the details. Maybe use some separating lines and play around with the colours. And last … your background is kiddish!!! Maybe use a different colour … or a gradient of other colours!
Thank you very much, i will work on it.
Design looks good. Agree with Luis, they look a bit of low resolution. Also text, you may need to work on text as they look just to be hanging out above and below each other. Give them their own important place and make them more legible.
Good luck
