Simple and effective, this is exactly what the challenge was supposed to be : a leading line pointing to the subject. Would have prefer less sky tho, to put more emphasis on the subject. I sense the sky do not add value to the picture. Having the camera closer to the road could have been fun too.
Though not overly complicated, I like your image. It is simple, and simplicity is best sometimes, like here. The roadlines, and horizon lines work your eye to the cyclist quickly and uniformly. The composition adds a sense of urgency, while leaving it open, creating a sense of freedom in his urgency as well. Neutral, natural colors give this picture realism and life. I like it. Good job. Possibly cropping one third off of the left side a bit might have intensified this image by taking out some of the dead space.. and enhanced the image.
