Good shooting, Bruce. I wouldn't get too carried away about depth of field. For this kind of thing, f/8 and zone focus pretty much gets the job done. Problem is that if you pinch the aperture for more depth of field you cramp shutter speed and end up with movement, though this becomes less of a problem as ISOs increase. The most important things (with any photograph) are subject matter, composition, and light. You've pretty much nailed all three in these shots.
