There are two ways you can put together your portfolio: 1. With an Open Portfolio, which is made up of 10-20 images of your best artworks, OR with a Structured Portfolio, which includes 3 illustrative portraits of yourself / someone you know, 4 narrative images, 3 landscapes/interiors, plus any personal work. Sketchbook work can also be included in the portfolio by editing together your favorite sketches or pages.
OTIS wants to see creativity and technical ability, observational skills, and experimentation. Applicants are encouraged to have at least one series in their portfolio. A series is multiple works centered on the same idea or theme. 2-3 may be sketechbook pages. At least 3 of the images should be made in traditional (non-digital) mediums.
