You've pulled off a nice idea very well. Composition, exposure, and lighting all very nice, but the composition is just a bit crwoded at the bottom right corner. Very crisp colors add lots of impact. The black/white border does not work for me.
Nice shot. Great composition. The specular highlight along the edge of the blade is a little distracting. Too bad it's a Wüsthof instead of a Henckel! That would have made it perfect!
nice shot. would probably like it more with less of the marble and more of the subject matter. good lighting. lettuce is a little soft; try extending your dof.
