A very neat shot - if perhaps a little dark overall? The EXIF stays that flash was used and yet your ISO was up in the higher 400 area - I would personally risk more flashlight (or use reflectors) and get the ISO lower so that noise is no longer a problem (especailly if this darker look is one you are aiming for)
And I am curious now as to what setup you used to get the shot - a standard lens you say?
