I've looked at this thread three times. So I'll just throw my thoughts out there and if anyone cries I'll apologise in advance.
1) I get what you've tried to do but it's not really worked. If you really want to portray her as posh maybe you could have shot a full length image of her standing below the sign holding a bunch of shopping bags from designer shops. Or leaning out the window of a Rolls Royce. Instead you've got a composition that I'm not mad on with a bunch of window/door frames offering loads of distractions, all to get a word in. But there's nothing about her that says "posh" for me.
2) This is better. She's pulled off a nice pose and I'm not overly bothered by the fact she's looking OUT of the frame. But I wonder if you could have done more with the graffiti. Having her a long way in front of it might have resulted in some interesting background blur.
I'd be interested to see more from this shoot. If it was your first time with a model it would be nice to see if you came up with any more traditional portraits?
