I gave this a ten during the challenge; I obviously loved it. I don't have a problem with the yellow at all, and think the wonderful B&W conversion with the minimal (though not necessarily subtle) selective desat is really effective. Thought it would have placed higher (but I only picked two of the ten best as my tens, so I'm not the typical DPC voter, I guess).
I really think that the road works very well with your shot. The yellow with the B/W is very nice IMO. Maybe a slight tighter crop would have been better IMO to get rid of the sky and top of mountain. But a great shot non the less.
Really like your idea here...but think the yellow should not stay the same intensity the entire way...off in the distance it should be less powerful than right close to the camera, to make it look real. It still looks good...really like your B&W.
