Ahem, my samples have subject matter which you obviously discount. Which none of your sample's have.
I'm not seein' any such merit over mine in these examples, and not that it matters.
The interesting point is they were shot with Canon bodies. I exposed mine to render the incredible sunset color gradient that evening and yours...
Well, they just sit there. Artistically boring, but they might make good stock images where that doesn't matter.
Do you think you could have exposed and processed any of them differently to make a more compelling image?
I do, despite the Canon limitations on the sunset shot.
