Create photorealistic image of "fantasy egg"

I want four variations of an image of a mysterious glowing egg. The Egg shell will have a texture like this: [login to view URL] The image itself will also have slimy roots under the egg. Two variations will have a blurry shadow of a monster (must be very vague and mysterious), and the other two variations will just be the plain egg. Make it a simple but powerful image. This will be used for a background of a poster I want to make. I don't know yet which color I will use, so I want to see two variations that are white, on a red background, and two variations that are red on a black background. But for the final delivery, I want only the pngs of the egg/root image. In summary: 1. White egg/roots without shadow (red background) 2. Red egg/roots without shadow (black background) 3. White egg/roots with shadow (red background) 4. Red egg/roots with shadow (black background)
