While I don't vary too wildly in hair color and style, when I do change it up a little it's helped me practice poses and facial expressions and pressing the shutter button and then running to get into place.
Here I decided to go a little bit more red. (I can't go much more without removing color first.) Since I am using my old wedding dress for a costume this year, I wanted to get a few last pictures of it before I started trimming and adjusting.
Some fun with low light and long shutter times. More experimentation is needed with this.
