Minimalistic Poster Design for Feature Launch

I need a set of poster designs to highlight the launch of our new WhatsApp booking support and live tracking feature. The posters should have a minimalistic and modern style, aligning with our brand image. These will be used for physical print materials, specifically at an A4 size (standard paper size).

The aim is to effectively communicate the new features to our existing customers, ensuring the design is clear, engaging, and visually appealing. Please deliver print-ready files in high resolution. Let me know if you have any questions or need additional details to get started!
