Christmas Tree Picture with Perspective

Move the camera position down low and the Christmas tree gets a new perspective. A longer focal length was used for this shot than the previous Sigma 10-20mm f/3.5 DC HSM Lens Christmas tree sample picture, but the lower position dramatically changes the orientation of the windows in the frame.
 
An f/11 aperture was used for this shot - to get a bigger starburst on each of the Christmas light bulbs.
