This sounds like fun to me, especially since my last name is Peacock!!! I would love to come up with something for you incorporating peacock feathers. I would probably stylize them a bit to keep it childish, and incorporating the blue and green will be easy since those are peacock colors anyway. I love doing small projects like this and I thrive with project layouts and design. I have two great kids, so aiding in the celebration of your little one would be amazing. I'm flexible with designs and I will make sure it's exactly what you want. I'll probably use photoshop to create the image and that makes it easy to save it as different file types depending on your needs. I can't wait to work with you if you choose me!
