I was thinking more like this.
When I cropped the image I kept the proportions the same.
There is no wright or wrong, merely interpretation. Just keep shooting, it's the best way to learn. Once you get bored with the cyber shot pick up a DSLR. And always remember to have fun
....also, with dramatic lighting like this, try experimenting with reflectors to cast just a little light in the dark areas to bring out some detail. Reflectors can me made from just about anything. Comic book boards work well, tin foil, etc., etc.
