Actually, the police sketch artist gig was more depressing than anything. I would often be interviewing victims in their hospital beds. My first chore was an 80 year old woman who had been raped and beaten by a 20 year old man. As far as getting details of a culprit, it's pretty much remembering a basic art lesson- the 3 basic shapes. "Was his head squarish?" etc.
Thank you for your kind words. That is a nice web page you have at http://trishmoreno.blogspot.com/ You are very diverse. I agree with you I just love the pencil. When the kids get older I will have to make room for painting again.
