I just stumbled upon Jila Peacock’s work! Quite unlike the historic examples I had seen (which are also possibly from the Middle East), she writes in the Persian Nastaʿlīq style, with strokes of a consistent width. Really unique. She recently published a book of Hafez’s poems – I hope to find a copy somewhere! Take a look! http://www.jilapeacock.co.uk/prints.htm
