I used a steel nib dip pen for this piece, I've really grown to love the way it puts down a line as apposed to felt tip or tech pen.
The original art work was a fresco by Leonardo da Vinci using an experimental technique that failed. Only copies of it remain and this drawing was done using a study made by Peter Paul Rubens.
Thanks, I have made studies of 19th century engravings to learn a more refined crosshatching technique. Strongly recommended if you wish to give it a go.
you did a good job, i really like it!
