Wedding Reception Theme

As the planning continues we seem to be developing a romantic, nature theme. Our cake has tree branches and birds similar to our invitations.   We also love the idea of having trees as center pieces at the reception. We are truly inspired by the photo on the right.  I love the all around look.   I want lots of emerald/jade green with black and ivory complements as well as silver accents.   I wish I could just pull my favorite parts out of this photo and just place them in my wedding.  That would make me truly happy.   I'm still  looking for more decor and things to guide our theme without making it too cliche.
