I agree that having gummies fill the photo would be the way to go here. One other suggestion I'd make (two actually...) is first, use the red/orange/yellow ones in the background and have ONE green one in the image and put it in a "Rule of thirds" position. I'd also shoot at a high, overhead looking directly down angle to get the maximum sharpness throughout the image. Great idea though and if you do take these suggestions, I'd love to see the new image posted here so that we can all admire your work once again.
