Garden statues (like your garden) should reflect your personality.  The most important thing to consider when choosing the right statue is to pick one that you really like and that you will enjoy for years to come.

If you like unusual things then you may want to choose a gargoyle or garden gnome.  If you are more traditional you may want to choose animals, children, or religious figures.  Whatever style you decide on, be sure that is one that you will love.
