For tomorrow you need to find 3 illustrators from http://www.art-dept.com/ (from the homepage follow the illustration link, then click the thumbnails to explore each portfolio).
Try to choose illustrators that cover a range of approaches and use different media. For each selected illustrator print out 2 reproductions of their work at a reasonable size (A5ish).
You then need to write approximately 200 words on each illustrator, find out what you can about them - where they trained who they have worked for. Most importantly analyse the images you have chosen, identify what media have been used and discuss technique (expressive or controlled?), composition, use of colour. Give your personal opinion on the work, but ensure you give reasons for the views you express.
Present the work thoughtfully (I'd suggest one A3 page per illustrator), think about layout and text/titles etc.
Tomorrow you will be doing some quick drawings of the figure and taking photos to develop your illustrator responses from.
