This is a good foundation! For flyers, we should consider the user experience, how the user will interact with our material. That being said, the details are too small and quite difficult to read, especially when paired with a bright green background color. It's also a shame that the sandwich was covered, unless that's what you were going for, in which case, you may want to center the sandwich so our eyes dart directly onto it. Can't wait to see more of your work!

very good buddy
