Thank you Leslie, Michele and Joan.
Leslie. As you will see in the new image I have taken note of all your advice and worked more on Taline, I was a little nervous about putting too much reflected light on the side of her face and under her chin because I didn't want to overemphasise her puppy fat too much. Thank you for pointing out the error in her hairline, I really had not noticed that at all and I think that it has made quite a difference as to the fullness of her face.
I have come to now realise that most of the problems that I had were because of my trying to 'slim' her down, it doesn't work and I learned the hard way. I was so intent on carrying out the parent's wishes to slim her down that I completely overlooked some of the differences that were staring me in the face!
Thank you everybody for looking and helping me out on what has proved to be quite a difficult portrait. I will never agree to make major adjustments to photographs again, if you consider what I am charging for it , which is peanuts by the way, I have worked for way below the UK National minimum wage
Take care.
Barbara
