Neat take on the egg idea. The dark background sets it off well but has the side effect of making it a little too staged-looking, sort of a trade-off. The egg-holder is itself interesting to look at, and makes a good contrast for the egg yolk.
The lighting needs work - so does the composition. If you want us to follow the flow, show it to us. Interesting perspective into the heart of the egg, but kinda gross around the edges. Nice use of negative space.
The symmetry of the egg is offset by the lack of centering the subject. The colors are intense and the link between the light yellow of the egg cup and the darker yolk provide a link. The running of the soft yolk is visceral and gives the picture some "live action". I think this is an unusual subject and just a great composition.
