#1 - This one looks too soft. I also think that making the shot a little wider or a little tighter would be nice. If more detail could be added to the hair using lighting, a wider shot would look nice.
#2 - I agree that it would be nice to have more of her hair in the shot. It might be interesting to make the snake naturally coloured while keeping the rest as is. I like the lighting and colouring. There is a blue spot on her jacket,left side. I really didn't notice it until my wife pointed it out.
#3 - On this one, my eyes are first drawn to the fur on her hood. It seems to be blurred so much that it distracts me. Next, my eyes are drawn to her right cheek. Overall, her face seems to be pretty soft but there is an area on her cheek that looks very sharp to me, like a rough patch. There is also a noticeable light circle in the dark oval on her right cheek. I would like to see this one in colour with less processing.
There is a large dark oval shape on her right cheek, in all three photos. Is that her makeup?
I do like all three of these. I would like to see how they looked straight off the camera so I would know what you were working with.
