Either your camera was slightly crooked or that's one helluva hill. If it's the former I think you need to correct that a bit. Nice action shots though.
Higher ISO next time..I liked the third shot in the set.Nice colours Jackie. Next time try bumping up the ISO to achieve a faster shutterspeed, your shots are suffering from motion blur! which is having an big impact on sharpness, look forward to some more, [/URL]
