This is the famous Duomo in Firenze (Florence) - one of the most amazing structures I have ever seen. When I uploaded my photos to manipulate them ready for transferring, the line work and contrast was really strong as a result of the pattens in the building itself. The dome is easily recognisable as the Duomo which was what I was hoping to achieve.
Some subtle colour highlights have been added using watercolour.
