Paco, the reason for you placing the first image at first seem is self-explanetory to me. The pose of the dancer, the framing, the flare...everything is in place.
The pose doesn't necessarily remind me of flamenco, though. Is it a flamenco dance of a modern creative style?
I wonder who the model of the tatoo is? Carmen Amaya? Madame Butterfly?
Having said that, I kind of sense that you were not very inspired while shooting these images, compared to your more successfully strong images posted so far. Hope you to improve the situation.
