Realistic Ephesus Library Pencil Drawing

I have a favorite vacation photo of the Library of Celsus in Ephesus and I’d like it transformed into a fully-rendered colored-pencil artwork. My goal is to hang an original, realistic piece that feels true to what I saw on site, so natural, historically faithful colors are a must...
