Yep yep, I am! :)
And usually, specifications of what to include in a portfolio usually all depend on the college, as well as what major(s) you’re going for! For where I want to go specifically (Ringling) and what I want to apply for (mainly Illustration but also Computer Animation), hands, feet, human figures, animals, representational drawings, and interior/exterior environments are asked for.Pretty much examples from drawing in life.
And, I personally figured this was the case anyhow, but a woman that worked in the admissions office for Ringling that I had a few minutes to talk to after my campus tour mentioned to me that they often look for works made with traditional media, as it’s beneficial to learn about art/animation from its roots, where digital art wasn’t really an options yet. :)
Soo not just sketches, but any paintings, sculptures, or anything that qualifies under their ‘requirements’ for portfolio content will do!
Though, your portfolio should portray what you typically draw, what you like to draw, etc.! Alongside the main stuff, you can include other things you may happen to like to draw, like character designs, animations, examples of storyboards, even a few digital pieces. (Though digital work should be a very small portion of your portfolio as, again, traditional work is what they like to see in your portfolio.)
I’m speaking mainly from numerous tips given from others and Rngling itself, but it still varies from college to college! Best bet is to usually refer to the websites of those that you’re looking at! :)
