Nice landscape, I think more contrast and (I'm a monochrome freak) maybe some desaturation.
The capsized kayak shouldn't be there... but then it wouldn't meet challenge!
Pretty nice landscape. think the subject of the photo is the kayak in the creek and it appears to be waaay to far away. There isn't really anything to make this stand out as being above average. You did get a good leading line with the stream at the diagonal and the sky in the top third of the photo.
