Inspiration: Charles Rennie Mackintosh

Charles Rennie Mackintosh is the most famous Art Nouveau artist from the UK and a designer in the Arts and Crafts Movement.  He was an architect, furniture designer, and artist.
His style, largely influenced by the opening of Japan and subsequent release of orderly/organic Japanese art forms, was formal and rectiliniar, but also had the curvy elements of the art nouveau movement.  Since he was also a technical artist, you can see that in his work as well.
