The whole family likes to watch the hummingbird action here. Tommy and Tigger spend hours on the screened porch everyday. They never seem to tire of it and neither do I. These cat sketches each took about a minute and a half and the hummers, well, probably about 5 to 10 seconds each. I used a soft 5B pencil and my big pad and drew holding my pencil like a wand, using my whole arm, large and fast.
