Christmas Arrangements 2

The date 12/12/12 this year is very special and unique. It's my birthday. My husband bought me 12 roses (red and white) for my special day. I am delighted to use them for my Ikebana class.
Here are the two Christmas arrangements: the first one was done at home, the second one was done in class.  I thought that it was an abstract ikebana arrangement and that it was inspired by the Sogetsu master, but my teacher said it is western styled. I am really confused!

Red (rose), green (pine) and white (twig) are the basic
 Christmas colors.
