Awesome silhouette shot. Great detail in the bike and rider. I like the sky, and terrific composition. Catching the setting sun where it is, perfect. With the light and the gradient moving from lower left up across the photo, it just adds so much to the movement of the bike. Great flow, and a great feel to the whole image. Very nice.
Very nice and powerful shot. Great sky and the silhoutted rider looks terrific. Being nit picky - I would say to clone out that one "stick" near the tire on the lower left side. Otherwise, well done and good luck in the challenge.
