More play with photoshop.
I made each of the eggs as separate images at first, glass-coated them for shine and then arranged them in a grass background. Then i extended some grass up over them to make them look like they're actually IN it and not hovering on top. Then i burned in the grass under the lambs and eggs for some shadow and depth. Also burned the eggs a bit underneath for shadow. Made the sky in the usual way. The lambs were taken from photographs (aren't they CUTE?), selected and transformed until just the right size. The challenge was trying to make them look like they were in the grass and not flying around above it. (I admit i had fun making them fly around for awhile first) Shadow/burn and cloning the grass up over their feet slightly helped. I learned a lot while working on this.
