Nope, not a bad thing to say at all. You have a good eye, and I'd have to agree that I didn't really get a good sense of motion in the first sketch. For one thing, I'd been working in ballpoint, so when I realized that the back legs were a bit too long/not high enough up off the ground, I couldn't correct it. That error "slowed down" the drawing. For another, it was a much flatter kind of source photo -- a straight-on profile, at a distance, and almost a silhouette.

What I loved loved loved about the photo I used for this one was all the movement. It was taken at much closer range, the dog is sort of going in multiple directions at once, twisting around like that and then the tail flipped up, and he's so full of great curves and angles.

And I just learned that his owner wants to buy the drawing and commission another thing, an oil portrait, I think. So: BONUS!
