I thought they looked great Bob, especially given your (self imposed) old fart status.
If only mine could get close to the quality of yours, and I have too many panned shots with only half a car or even empty tracks to count.
I have moved on to taking mainly paddock shots these days... and im still, relative to you, in my nappies! I struggle to open or understand the menu on my (Canon) camera!
I guess what I am saying is that if you hadnt mentioned it I wouldnt have picked they were at all substandard. In fact even with your heads up I struggled to find fault.
Keep 'em coming.
