Nice take on the challenge. Although it looks like you might have a small hill on the right, the horizon looks a bit slanted. I would have rotated slightly clockwize to minimize the effect. The egg looks very natural in this setting, (doesn't look staged) Nice job.
Good idea but not very well performed. The image lacks sharpness, the colors are litle strange and the egg is "shabby". Think that better formed egg and maybe a litle higher angel would have made this one better.
