I like this, it's not to "posey". Especially her hair and the black and lighter parts it gives a perfect balance in the picture, it's a clear favourite!
This is a really lovely, intimate shot..completely natural and at ease. What I noticed first was the grain, though -- from a 400 film, it seems more than usual (although it's a very appealing look, the grain is lovely).
@ Colin: the grain you see is NOT the one of the film BUT the one of the PAPER. That's it with Lith printing. So yes it's deliberate . With lith printing, paper grain is exalted and that's what is lovely
