These are very good and very worthwhile,my advice is to keep at it trying different dishes and angles of shooting,also I would vary the DOF untill you find a style that pleases’ you. Might be good to study how the pro’s do it in food magazine’s newspaper advertisements etc. look forward to seeing how it develops for you.
Sharon, you love food, you can tell and you are photographing what you love and that really makes sense :D You also have a natural flair for composition, so you go girl.
