I think the critique was a little short, so let me add a bit :)
Good idea to put the egg on the mirror. A few people did that, but not quite the way you did. What is not very attractive is the white gunky stuff which is in eggs. That stuff makes me think of phlegm, and make the image a little less appealing than it could have been. The other thing I find offputting was the splotches of egg white which didn't want to remain in the frame. It would have been almost like a leading line to have the bottom splotch down at the bottom of the frame inside, which would have added continuity. I hope that made sense.
Things I really liked: The lighting is superb. Absolutely magnificent. I like how there is no glare on the egg, and just nothing is over exposed at all, which is almost a miracle. I also like the simple colour scheme you have here of the egg yolk and the white of the shell. It's so simple. I'm not sure if you meant for the grainy feel on the top of the egg shell, but there's a program called Neat Image, which you can get on the internet (just go to google.com and type neat image and it pops up), which will get rid of graininess. It doesn't always work, but sometimes the results are stunning.
Well, good luck in the future challenges! You've been doing great so far :)
I like this idea. When I look at this image, my eyes go to where the interesting light is: in the clearish yolk, but I would think that you'd want the interesting light on the whole egg.
Yuk, this is a great shot :-) I hate the glibbery stuff in eggs! Good lighting and the mirror effect is cool. I only find it a tad grainy, especially at the top of the photo, but otherwise an image you can be proud of.
