the first one just doesnt interest me. The second one i really like, but it seems as if there is a lot of noise in the rocks? OR is that just me seeeing things?
I really like both shots. On the first one Ive just straighted the verticals and lightened the building on the right a bit and cropped for a pano look.
Overall, I think its a really nice use of HDR. My only nitpick is that I might've turned the saturation down a notch or two in both for a more realistic look.
