See my blog on outdoor garden statues
A garden design like this would best benefit from outdoor garden statues that are specifically chosen for the nook they will be placed in. It is also important to keep contrast in mind, with regard to how well your outdoor garden statues will work with the other elements in your garden. You may later realize that a piece that you thought inappropriate is actually the best choice for a particular spot. You may find that a more contemporary piece makes the perfect foil for a traditional garden design for example. Don't disregard the whimsical approach either.
