Great perspectives and angles. I especially like 3, the really contrasty bw one. Not a fan of the last one, but more selective focus might be able to change my mind. In general I think they could almost all benefit from a 1/3-2/3 bump up in exposure. If it were me, I would be inclined to use shallower depth of field (I'm a sucker for bokeh) and either pump the colors or be a little less subtle with the desaturation. One way or the other. But great subjects, good eye.
