Nice shots. I realised how much I enjoyed photography whilst taking photos at racing events. Unfortunately I also realised that I'm not very good (yet) at motorsport photography. I like your images, the cars are all very clear and well focused with lovely motion blur in the back ground. the space in front is good for movement and the images are very well composed. True, they are all from the same angle etc, but we will await more.
I am very lucky where I live as I have Brands Hatch racing circuit, Arena Essex Speedway and banger etc oval circuit, Canada Heights motorcross track, Lydden Hill, Lydd, several go kart tracks and even a couple of grass track ovals all within easy reach. Just need to nail those pesky high octane shots now.
