Carlo Stanga is an Italian born illustrator currently living and working in Berlin. He works primarily in a loose but often precise and detailed style of line and color, using a variety of media.
He plays with the conventions of line and color, sometimes using color for the lines themselves, sometimes losing the line altogether, often within the same illustration.
His detailed illustrations are often filled with fun details, even cut-aways of trains or buildings within a larger scene.
You can find a gallery of his illustrations on his website, as well as additional image in his shop, where prints are available.
There is an article about Stenga on Moleskein.com, an interview on Molteni design magazine, a brief video on YouTube, as well as a video review of Sranga’s his book I am New York by Teoh Yi Chie.
There are English versions of his books, I am New York and I am Milan (Amazon affiliate links).
Stenga has also created a Domestika video course: Architectural Illustration Tutorial: How to Refine Drawings of Urban Objects and People, for which you can find a video preview here.
