Hi Cynthia,
I don't mind your suggestions at all. In fact, I welcome them. I will give your method a try.
These portraits you've posted are great! Thank you for sharing them. I certainly hope you post more of your watercolors in the future.
I see what you mean about glazes of color, especially in the boy's face. I love the way you did the little girl's bonnet! I wish you lived here in Louisville; I'd take classes from you.
