December Self Portrait

For the 12 Days of Christmas photography class I'm taking, the pre-class assignment was a festive self-portrait.  Since I collect Nativity sets, I chose the first one I ever bought (a egg shaped one from El Salvador) and a ceramic angel made by my mom.  I had intended to take one of me holding the angel holding the Nativity, but I liked this image much better. Although it's technically a self-portrait (that's my hand), I think it's a bit of a dodge not to include your face, so here's the other SP I took:

To take these, I hauled a full length mirror outside. This is a technique I've seen before, and I reallly wanted to try it. Since I was in a rush, I only got as far as the back deck. But I like the results, and some time I will take the mirror all the way out to the back field and beyond.
Got any good self portrait tips to share?
