I like this one, Jim. BTW, we have too darn many Jim's and James' here! Nice rich colour, in both the arch and the sky. I like how the arch is set up to show the mountains in the background. Shooting it offset like you did gives it a nicer appearance (and likely enhanced the light for you). I find my eye wanders the whole composition, coming back again and again to the bright side of the arch. I'd say you did a very good job on this one.
