The image started of in Poser where I made four poses, (two of each figure), each figure has a skeletal pose and a fleshed out pose. These figures were then imported into Bryce and the skeletons were given a steel texture, the fleshed out poses were given a glass texture, also added at this stage was the buildings. The image was then opened in Photoshop were blur effects, impact flash and glass shatter were added.

Prior to creating the image above I had experimented with similar ideas, please click the thumbnails for larger versions...
