This is a decent shot that meets the challenge, I think there are some excellent points of interest shown as well.
That said, I find the tone and colors a bit lackluster. Maybe a filter of some kind may have helped, the tones are a bit washed out maybe from the natural light.
I think a shift (if possible) in the composition so that straggly bush wasn't in the picture at the left would help since it doesn't really add anything to the image. Also perhaps a different perspective could add some drama to the photo.
I do like the way the rider and the bike line up, I think that parallel look adds interest. I also think that the location is good, with richer colors in the water it might pop more especially because the bike would likely reflect the colors tying the image together nicely.
Overall it is a good shot, just needs a little extra something to it. I gave a 4.
I would have liked the camera position to be a bit lower and to the right to make the image more stable and thus more tranquil - this would also render the shadow complete - the stalks behind the head should be clipped trimmed or PS'ed out ... nice overall concept and light , not to mention ... nice BMW
Dude! When everyone else is at the beach, you should be smoking some rubber on the empty twisty roads! :) Cool bike, never ridden this one but I am familiar with the engine.
