Kind of a fun idea for a shot. I like the placement egg in the lower corner. Now get what needs to be in focus, in focus (like the egg) and experiment with lighting angles and/or levels of light to increase the drama and interest.
a hard one to focus on. the crop may have been too much. better if egg would have ended up in the bottom quadrant "of three" with a bit of the rest of the mirror exposed on the left side
The reflection was a good idea, but the main part of the picture is a bit unappealing IMO, perhaps you could have tried for a larger reflection of the egg.
