The green, out of focus background is nice. I might have tried positioning the egg so that is the only background. Farther back on the table perhaps. And away from that dark window frame (?) on the right.
Interesting subject, but out of focus and composition uninteresting. I'd zoom in on the center portion, or maybe zoom out to get some more space around it, perhaps add something else into the subject.
There are some hairs or dust near the top which is a little distraction. It seems the focus is a little soft. The shades of gray are very nice. The backlighting is not too harsh.
