for my taste a close up on one of the details could have been stronger than showing the big view. very challenging and interesting formation. the big view and the bright sky makes it difficult to capture lots of details. It seems as if you took the picture handheld, very soft.
The sky feels a little blown out. Maybe using a Neutral Density filter you could have retained a little detail/color. Sorry to keep picking your photo apart but I would've liked to seen the image rotated just a smidgen to the right also. I'm guessing that the ridges might have ran at an angle but that was just my first impression (to get them more vertical). Overall, it is a great picture. -BB
I really like the basalt(?) columns. Their sweep down and to the right is interesting and unusual. The image is a little flat ... a bit more contrast might make it pop a little. In the end, however, it doesn't really say "architecture" to me.
