Hi Naka
Good image for Dangerous - as others have said, it's perfectly on theme and the overall dark tones to the picture work well. However, I do think the main area of attention - the knife and hand would benefit from a bit more light. That would throw a bit more contrast between the rest of the image (her body, curtains etc.) being dark and the knife and hand jumping out a bit more. Two ways to do this: either with a complicated lighting setup, or exposure the whole image a bit brighter and then use a radial filter or an adjustment brush in lightroom or whatever post processing package you use (if indeed you use one) to darken the rest of the area back to what you have.
Just my 2p but it's still a good take - well thought out good composition.
