Bridesmaid Bouquets

I've decided to make another compromise in order to save money, one that actually may end up being very pretty.  Since I have orchids and calla lilies in my bouquet, and orchids are very expensive I decided to go with calla lily bouquets for the bridesmaids.  They are going to be beautiful, and I think they should contrast well with the white bridesmaid dresses.  The green in the stems will tie in with the color scheme well, too.  Here is the picture I used for inspiration (fiftyflowers.com), and my bouquet inspiration picture (theknot.com):
