I do not know what you had in mind when you took this so if my comments fly off in another direction, sorry.
First, I think a more rectangular frame would help (crop some foreground) - it might convey a sense of motion whereas the nearly square frame seems static.
Along that line, the image does not, although obviously there was, show any motion (blurred spokes, foot/pedal, etc.). I guess there is a hint of motion in the second rider's leg....maybe they were coasting at the time?
Focus is good and gives depth to the image. On this monitor, which is not a good basis to judge, the sky has a green cast and, assuming the second rider's helmet should be white, it too, as do his socks, has a green cast.
Ty- I agree with Bob in that a "sense of motion" would help this shot out. I played around with it in photoshop and this is what I came up with (if you don't like it I'll delete it.) I meant to cut off the rear wheel of the rear rider to try and give it that "sense of motion."
I have to agree there isn't much sense of motion and the colors look a little off or bland?
Ken's version seems to pop quite a bit more, at first I didn't like his version but upon looking again I really do.
