Still working on the macro setting for photos

I am still trying to take some good photos using the macro settings on my camera. I thought that I had taken a good one of the crispy snow pea dish at a Thai restaurant yesterday but when I looked at it on my computer it was blurry. Too bad because the colors in the dish were really vivid green (snow peas), white (onions)and red (peppers)


I took about 10 photos of shells and this is the best one I got.
