Good lighting on the model that shows off the body form - Model's sultry pose matches the sultry sound of Santana's song/music. Good choice in going with the B&W for it really shows off the way the light falls (shadows and highlights) plus it ties in nicely with the 'color' of the song it alludes to. I think that the composition just needed one little thing that would give it a stronger tie to Halloween WITHIN the shot rather than relying on the title so much....not sure what I could suggest perhaps a small bottle that reads 'witch's brew' or a small temporary tattoo of a witch's cauldron or the words Salam. A witch's hat would have been too much - a subtle touch is what I think would work best so as not to overpower the model.
