Hi Jbtaylor,
The Tamron 14mm does indeed help create interesting photos out of interesting land formations...and bunkers.

I like you first series for the coherent similarities you caught in the differences of space. The white flowers bring a dimension to otherwise graphical interpretation.
I think both bunkers are looking good in their own right, but maybe the increased foreground distance in the second one works better for me. I feel the foreground is cropped a little too much at the lower side of the frame to fully give the impression of just how good an impact it has on the photo as a whole.
Just my thoughts.
Thanks for sharing. Any more like this ?
