Your blacks seem to be detail-less and "plugged up" or "crushed", to use the common parlance in describing them. Overall, the images look good, except for the loss of detail in the blacks. We should be able to see detail in her hair in the darkest areas, but we cannot. So, that needs to be fixed.
Apart from the above (and not sure about the rail in the background on the left side of #3, distracting?) I'd say they're good photos and I'll bet the (very pretty) young lady is pleased. :thumbup:
