They look ok to me, but if you want them redder, try selectively changing the hue of red more toward magenta and away from orange. I say selectively, i.e., apples only, as you might have problems with faces otherwise. As a matter of fact, the faces already look a bit too red. To diminish that "old" look in apples, try enhancing yellow patches toward green and increase saturation. Also, play with Clarity slider a bit to see if that helps.
