Untitled AI art by @AlexCooper

This is a square image, and I want to print it in A4 format. To achieve this, the image needs to be extended on the top and the right sides to match the A4 dimensions without stretching or distorting the original image. The extensions should seamlessly blend with the original image's artistic style, colors, and elements, making it look natural and cohesive. The final result should be in high resolution, suitable for printing.
