Probably one of the worst pollution we see on a daily basis.Something about the composition doesn't work for me, maybe it is just a bit too close up? not sure.
Lighting is not very good and the focus is off. Try to avoid direct lighting as it causes hot spots. I also would have liked to see the Disaronno label in the shot.
I think this would look more appealing if 1) the dof included the thumb, and 2) the lighting was not quite so harsh. I do appreciate the pollution reference though.
