I absolutely love this series, great mix of emotion and texture. I don't care for the halo in 1 and 3 and not because its a halo itself , just to my eyes it is distracting, my eyes tend to go to it before I take in the overall image.
I like the second one specially. The others are good too, but I like the composition more on the second. The catchlight on her eyes, the expression, her clothes, the dof... it's a great portrait, with a very warm and cold feeling at the same time.
I love the scene, facial expressions, composition is good. The processing is driving me crazy though. It's just too unnatural with the halos but that is personal preference. I think they would look much better blended a bit. Otherwise nice job
