Many thanks, Shu, Nico and Penny.
I am visiting for my work a city of Cagliari which is the main city in Sardinia, Italy. What you see on the picture is a tower which makes part of the medieval city walls. It was used for defence and as a prison during different times of its about 700 years of existence.
I definitely also prefer the colour version, alexeig. What a dramatic building this is. Would you care to let me/us know where or what this is?
I tried hard to think of something I could suggest for improvement / different, but I think this is pretty much fine, from my perspective at least. I know it is the type of image I certainly would also have tried some hdr techniques just to see if one can add even more drama to the scene.
