Portfolio requirements will differ from school to school, but in mine I included:
- storyboards and composition sketches
- highschool portfolio work (vcd, though I'm sure any media/arts adjacent subject would be fine)
- drawings from my sketchbook (they like to see your style, I was asked to bring my sketchbook to some in person interviews as well)
- digital art (majority OCs, some places are iffy on fanart so I would generally avoid it),
- stylised environment art
- some life drawing (only a few, objects and plants)
Some places will also allow you to send animations you've already done, either by email or a link to somewhere online (the ones that did, I sent the animations separately but it might be more worth it to make a showreel that you can then frequently update with course work)
Based on the art above, I'd include the life drawings, sketchbook pieces (though maybe get some clearer pictures?) and a collection of your digital art - if you have work that shows more variance in shape design then I'd also include that. I like the comic panels too because they show you can visually tell a story, but I'd want to clean them up/finish them for the portfolio. Your art looks nice with a bit of a unique style, which I think would appeal to whoever is going through the applications! For an animation course, I would prioritise personal style, dynamic drawings and some scene/environment art over life drawing, but it's still good to have on there to show that you know the basics.
I got into the top school for animation in my country, but my portfolio was very rushed and thrown together, not pretty at all, basically just images thrown together in Word - this was also 2022 and probably a different country. I did get into all of the universities I applied to, but still take this with a grain of salt, I'd recommend looking online to see what past SVA students submitted.
Wishing you luck!
