Mr Goat? I hear you like tin cans...
Something about this shot doesn't work for me - the dark spot in the background is distracting. Also, it is not obvious what the background is, and it blends a bit too well and not well enough with the tablecloth / place mat. It feels to me like elements of the shot are competing rather than blending.
Maybe it is just this simple - I don't like the combo of the baby blue to white and the dark blue of the can (pastel vs. primary colors).
I would suggest not clipping the edge of the sandwich (the lettuce) when cropping. Maybe centering the top of the sandwich on the can would have eliminated the need to do this.
