Well spottedThe only thing that looks off is the artifact to the right of each bean. It wouldn't logically be shadow, with such powerful light coming from that side, but if it is soft shadow from the softbox then something happened to it.
It's from the softbox. The surface is light green cartridge paper (my original plan was with a different box but it was a bit bent) - they are brown reflections of the shiny coffee beans which being dark and brown have soaked up a lot of colour from the adjustment layer.
I'll see if I can fix them.
Edit: I've done some work on the double shadow, replaced the image and left the old one up as an attachment. I was looking everywhere except under the beans for double shadows
