Almost nailed it with this still life. Contrast is a bit dull though. Some adjustments to bring out the texture and colors would have improved this. Some variation on the lighting as well, perhaps, but I'm still experimenting with lighting myself. I'm not any expert in that area.
Nice shot. I like the lighting and the composition. I think it's a bit dark overall though, causing the jam to blend in with the background. For my taste, the dof is a bit short as well.
my first impressions: nice and warm colors; the butter in taking away from the bread (less is more); a bit more light bounced tothe bottom to separate the slices; the same for the jar (a slight reflection of light would separate the jar from the background). good composition.
