Thanks very much for your comments, mazzy and Andere. I would have liked to have posted them in entirety and, although I resized them to put them here, it didn't work out as expected.
I've been good at drawing faces ever since I can remember, but until I joined the local art group (about 2 and a half years ago) I hadn't done very much painting at all. I think I've come on leaps and bounds since joining so, I think you should both have a go yourselves, you might surprise yourselves. Get a good photograph of something you like the looks of and give it a go ................... it's only copying after all.
