What not to do...

Below is a perfect example of an opportunity being wasted. This is a picture of my sister and as you can see, the composition has ruined the picture, mainly because I cut part of her face off. I really love the lighting and the lines in the background are great, naturally leading the viewer's eye to her face. The worst part of this situation is that I didn't take advantage and snap a few more pictures until I had one I could use.
