Dark ruins aren't my next phase (unfortunately we haven't got enough ruins in Holland to make it a phase), I just found some old holiday photos when backing up the ones from Germany.
This is taken in Fort Sint Pieter, Maastricht (the Netherlands). It was created in the year of 1701 to protect the city against the French. The 'windows' you can see here are actually places the canons used to stand.
--- Post-processing: I upped the contrast and made the dark parts just a tat lighter. The shadows and all are natural, just like the darkness in the fore- and background.
My photos are NOT stock. This means I do not want them to be used in any way. I don't mind them being used as a reference for a drawing/painting though: please visit this link for the rules [link]
