Thanks guys, quite happy with them for my first attempt with the DSLR - although it would have been nice to get some shots on the outside of the corner on the other side of the crossroads (in Brechfa), as the cars were totally broadside kicking up mountains of dirt - would have made some superb shots.
I'm hoping to get a new lens for Xmas so watch this space in the new year for shots of the Red Kite rally in January.
