Hi Kim,
This is all good (and interesting) advice. I paint a lot of older women and I really enjoy doing so. I go out of my way to reassure them that I find them very beautiful and I am going to do the very best that I can to make them look fantastic. To do this you really have to believe as an artist that it's not just the young women who are interesting. (I have a vested interest in taking this position, by the way.
)
I never hesitate to find the most flattering way to look at somebody. Let somebody else do the wrinkled character studies - it won't be me! Remember that you can do lots of "easy" steps such as lenghtening necks and fingers and taking out jowls and you will still get a convincing likeness and make your client happy.
