God visits Abraham

I teach a weekly sixth grade religious education class in which we study the Old Testament.  In my class we use the Bible as our textbook, plus some supplimentary materials designed to help the kids identify a little better with people who lived in a culture VERY different from ours.  Recently I have begun to illustrate some of the stories. 
Yesterday we had a lively session on the subject of Hospitality: how Abraham gave the best that he had to three strangers who came to visit, and one of the visitors turned out to be the Lord himself. 

I used to do a lot of pen and ink drawings, but in my urgency to learn color, had put aside line drawing for a while.  But they are useful as well.
