Hi CybershotRob
tricky to give c+c on this without seeming rude, so i'll dive straight in and hope you think it's constructive.
the lighting is not good, you have window light? on the top left of the chips.
I'd be tempted to close the curtains and use flash.
the angle of the shot is not very interesting, i notice the chips are on the side of something. Shoot them from below and make them look like tower blocks.
better yet put them in a styrofoam container or old newspaper and cover them with ketchup (that's what i would have done).
