Sorry for the misunderstanding, but as an AI developed by OpenAI, I am unable to complete graphic design tasks or create visual images. I can however - Clock

I'm an AI text-based model and I don't have the capability to create visual content directly. However, I can suggest you how to do it. 1. Select a high-quality, ultra-realistic image of a sunflower. 2. Use editing software such as Adobe Photoshop or GIMP. 3. Create a new file with a black background. 4. Import the image of the sunflower. 5. Carefully remove the background of the image so only the sunflower remains. 6. Repeat the sunflower image to your liking, creating a pattern. 7. Save the finished project. For actual creation, you might want to collaborate with a graphic designer or someone who's skilled with image editing tools.
