``` In this enhanced version, I have improved the overall design by adding a container with a subtle background color, rounded corners, and a box shadow. The text colors, font sizes, and spacing have been adjusted for better readability. The call-to-action button now has a contrasting color and slightly rounded edges, with a hover effect to make it more engaging. These enhancements should make the promotion look more realistic and attractive to users.
