Christmas Decorating--What to do?

I find Christmas decorating a challenge, especially in our current home. When we lived in a Victorian era House it seemed easier, I guess because I had a theme to decorate around. This house is more contemporary so I'm left with a lot of Victorian decorations that now seem out of place.  I continue to do my tree in a Victorian theme--my family has fond memories of all the decorations and tell me "it's tradition!" Here's some pictures of the tree and decorations. (It is a faux tree because daughter is allergic to pine.)
