These were one of the first things I did with illustration that I was very proud of.  We were given the opportunity during my program's third year to speak with former successful graduates to pick their brains and learn about how they got where they were and to soak up any tips or advice they had.  Only being asked to take notes in bullet form on lined paper I decided to take it a step further and sketch note every presentation.  I used a pencil and paper during the presentation then brought the rough notes and sketches into Illustrator to create the final products.
