So many to comment on.
Round 4, lovin' photo 70, blue buggy turning, shocks all compressed one side, tyres doing their best to stay on the rims, excellent action shot !
Round 5 photo 4 with the buggy charging toward you and the great Depth of Field you've got in with the blurry traffic cones in the background and the water spray all up in the air, shame there isn't a little bit more car, just slightly higher would have been better but they're all good shots
What gear are you using ?
