The most important thing is the communication. You should talk to the model continously and she will watch you. Regarding the poses I can suggest that you should look at many pictures (e.g. 500px.com, 1x.com, etc.) and try to reproduce them. I like in your picture that the line of her nose is parallel with the edge of the picture.

Best large to appreciate this open space and its BW range of tones Yes, I agree :) Me too. I particularly like its great tonal range. Nicely done my friend. :)

This is a much better portrait then the previous was. I don't like her hand in the picture I think that is unnecessary. I also cloned out the lights on the (her) right side of her nose because there is only one main light in the real life.

Great contrast and colours, stunning capture. :)

Nice sharp well detailed capture. I do like it.

Well spotted and captured love it nice piece of street photography I agree with David, this is a great capture.

Lovely night capture.

Nice geometrical composition, lovely conversion. This is a great capture.

Nicely done long exposure shot.

Nice moody capture my friend. I like its nice tonal range and the great composition. :)
