Well I need some help. I am taking a portrait class, Faces in Technicolor by Sharon Tomlinson. Her blog describing the class is All Norah's Art . This is my very first portrait and I am not really ready for them but I wanted to learn how she adds all the colors to them.
So where I need help is with my drawing. I have pointed out what is wrong with the pictures many of you were asking for help on and I am now asking for help myself. I know the mouth needs a little change which I saw when I was uploading the pics but beyond that, what do I need to do to make this look like my grandson? Your advice is most welcome and needed.
