Portrait of a book launch

I drew the authors of a new book on learning, education and games at an event in NYC. I did pencil sketches during the talk, then redrew them at home with sepia Derwent Inktense pencils. They are water soluble ink so I then applied water for a soft effect. It's a little different than straight ink wash; there's a subtle pencil texture and the water softens the outlines. This is warm up for a larger portrait project of restaurant owners in Jersey City for a local magazine.
