A slight ccw rotation during cropping just the level the horizontal surface. The background looks a little pink on my display, adjusting the white balance to remove the cast might be another thing to consider
First thing I notice is the part sticking up on the cut apple. It would have been nice if that was gone, whatever it is. I wonder what this would look like with the saturation pushed up a bit and a little more contrast.
Very nice. I'd like it better if there were a third apple, the glare reminds me of eyes and I struggle to see the picture. I love the angle of the cut, though, the line down the second apple, the faint shadows round the bases and behind the first stem. Good job!
