The judging of the designers work is extremely subjective. Each person that sees the design will make their judgement based upon personal preferences for design styles and flower choices. There is no set of common criteria used in making decisions about whether a person likes or dislikes a floral arrangement. In fact, there is not a standard criteria list which is used by everyone. To further convolute matters, judging actually comes from more than just one or two people _ they come from the recipient, the customer who placed the order, and third party observers (anyone else who sees the arrangement). Therefore it is virtually impossible to please everyone with each design that is created.
Picking your flowers (and vase) _ When selecting your flowers, try to pick a few colors and shapes that will work well together. You can go with a monochromatic design (all one color) for a contemporary look, choose all warm colors for a strong happy statement, or mix every color you love for a natural feeling that will bring the outdoors indoors.
