Like this one - the black and white I thought works really well. Could make a decent poster even. The only slight personal alteration i might have made was to lower the position of the bike - seems a wee bit high... The bike is so in focus compared to the rest - you must have hands like a rock. You have definitely captured the spirit of the challenge, so 9 it is.
I really like this shot... Black and white was a good choice here also.. the contrasts are excellent. This photo seems to create some intimacy between the two on the motorcycle... great work :) = 10
I feel like i"m looking at a fabulous art magazine photo. Very professional looking. Very crisp. Great overall composition and effect. It's pitch perfect - 10.
