Like the third one the best. Tell us more about your spatial relation to the objects/mannequin?/etc when you set up this shot- the intersecting layers at various depths are awesome.
I do like the second one (2nd best to me) as well. The only thing I will say is that my eyes keep wandering around the frame (which can be good and bad). I think in this case its because of a slightly disconcerting DOF where it seems none of the facial features are in sharp focus (except maybe the details on the cheeks). I keep looking for something to anchor it - but maybe that gives it a certain hollowness that you were going for. Any way you slice it, it's an interesting shot.
Thanks Zatomik for your comments. Image #3 just had potential when I looked at
it because it had mirrors all around and the trick was to decide where to focus and
what to include.
