Here is my second attempt at drawing on the Wacom Intuos4. This is a photo of a friend of mine; powerlifter Ben Brand. He's a strong dude. There's like 700lb.s on that bar...I'm not exaggerating.
Here is the photo reference:
Here is the first sketch. You can see that the upper body is too narrow and leaning forward.
Here is the second attempt. Closer. But not quite right.
All of this represents about 45 minutes of work....most of which was figuring out the software. Actual drawing time was probably only about 15 minutes. I'm pleased at the progress. But, I have a way to go. Adapting to the Wacom is more difficult than I anticipated.
