This is the final version of my pencil drawing, although not all of it is pictured. This final piece is 17" by 20" and is matted with a 3 1/2 inch mat. I am waiting for the frame pieces to arrive and I go to a local hardware store for the plexiglass. You will just have to come to the Shades of Gray show later this year to see it. I intend to enter the show with this. I have had a difficult time photographing this to my satisfaction, so even this one is not to my liking. I will try again when I send in my entry for the show. I did check on my use of perspective in the drawing, but it's one thing to get a drawing correct and another to do an architectural remdering. This is leaning on fine art, not architectural rendering. I did this without ever feeling that I was too stiff in my treatment. I used Stonehenge paper and several 6B and 8B pencils. It takes a delicate hand and iss quite a test of patience, but I love doing this and I never have a moment's frustration.
