Expecting the unexpected

It is not exact the Murphy's Law.  Photography, origin from Greek, is painting with light, is well defined with this image taken recently, using Canon 5DII, with EF 100/2.8L IS Macro.
Use mixed of studio strobe and light torch, in a 20 seconds exposure, resulted this image.  The model was mainly exposed by the studio strobe, and the traces of light came from the light torch.  The light from the light torch also cast some interesting shades on the model's fair skin, gave the final image some extra color.
