A simple composition, but difficult to execute. You've balanced the fill lighting just right to illuminate the pear evenly without excessively diluting the nice sharp shadow from the key light. It would have been nice if the secondary shadow of the stem was hidden.
Nice and simple, the shadow well placed extending out like that, also the slight shadow just behind the stem works in well. Only a very slight glare on the pear itself is distracting, but like I said, only very minimal.
Very good shot. I think I'd of liked this a bit more if you had positioned the camera a little lower. Still your light control is very good.....excellent in fact. Good colors and focus. Maybe a bit too much sharpening...?
