Wow if this is the way you treat new photographers who are just wanting to learn better techniques then may I'll go somewhere else. I understand giving technical advice but being a jerk doesn't make ppl want to listen to what your advice is. It's ppl like you that make people give up on that kindling of passion to grow as a photographer and never uncover or learn their true potential. So thanks but no thanks sir!!
Whoaaaaa there Nellie! Had you posted these as shots you'd done for a friend, you'd be getting all kinds of helpful advice, but since it was a paid commission, that puts you into the realm of the professional and things are measured with an entirely different type of ruler. These do not seem to be at the level that I would expect from someone who has the skill and knowledge to accept paid work. With respect to my earlier comments, I took from your comment about rolls that perhaps the client was unhappy with her body (something common to people of ALL body types), that was not the case, which should have made this an easy shoot. My comments regarding getting to know the subject were made because looking at your post, I see three rather uninspired headshots; NOTHING shows us who she is, what she likes, where she lives... in short, I know no more about her than I did before I clicked on the link to this post.
For future commissions, spend an hour or two talking to the prospective client, find out what they like, what their hobbies and interests are, and what sort of images they would like (and of course, since Mom & Dad usually foot the bill, it's only good manners to ask them too!

) With that information, suggest she spend a couple of evenings searching for examples of images and poses she likes. Then before the shoot, after you've discussed clothing, locations, etc, take a few minutes and plan the shoot together. Try and plan 3-5 shots that show: Where she lives, what her interests are, any talents or skills she might have, and of course a few classic informal portraits too.
For these, call her up, tell her that you're not happy with the way they turned out and offer to reshoot. Say nothing about why you're not happy, just tell her that you would like to re-do them so that she has the best possible pictures, and try it again.
Good luck!
