Dale, I apologize in advance but I just can't resist echoing Walker Evans: "It's a beautiful sunset... So what?"
I agree in principle - I think the reason we shoot these (those of us who do) and post them is because OTOH they are all different, and OTOH they're a good challenge, not just for technique, but for originality.
I trust you noted the different OTOH's and can resolve those by context.
If you look at my other sunsets and near-sunsets, I think you'll see that they are different, although perhaps not a technical tour de force(sp?)
