Your final results are certainly iconic looking in some respects.

Have another creative suggestion for you.

See here:

"Outcast: 2"

And here, for the actual tutorial:

"Sepia & Ageing Effects Tutorial"

The thought here is that with some adjustments/playing around with the settings mentioned in the tutorial linked to above.. might be fun, for one.

And more so, two ... bring out a lil' more detail in the shadowed ares.


Your base image is strong on the notes of composition.

Caveats?

Not sure that the following will make sense or no, however.. forging ahead ...

Smaller resolution looks better to my eyes.

Larger, there is some noticeable contrast changes with respect to the building's/structure's outside edges ('fringing', for lack of a better descriptor).. so, did you apply any additional sharpening?

Or, possibly..

Depending on the adjustments/post processing performed, change the Blending Mode to that of Luminosity to preserve photographic data (look at the histogram in your image editor.. if it starts to look like the teeth of a comb, you are losing data, simply put).

That said..

Interesting results, and I mean this in a good good way. :o)

Merry Christmas to you and your loved ones!!
