Always enjoy a drawing with this kind of shading, hatching and cross hatching. I even do that on the underpaintings of my canvas paintings.

With glass, I'm naturally drawn towards smaller formats and most of my glass paintings are within 2 square ft. The bigger your sheet of glass, the more difficult it becomes to handle. My biggest in one piece is some 30x80inches and it was a pain to do.

So yes, here's to the small format. Your drawing is awesome!!
