Heyyy, thank you! Berlin sounds amazing, that would be so cool. I found putting my portfolio together really tricky. I think put in whatever you feel shows your strengths and your style. And also put in what you’re happiest with and feel you can talk about if you get an interview. Maybe include some sketches and works in progress too to show how you work.
I love your animations you’ve just posted, try and put them on disc/USB if they let you so you can show them. And telling them you have a blog you regularly post too will really impress them too.
Illustration and visual communication is super good, I’m sure you’ll love it, it’s so versatile. Let me know how you get on and if you have any other questions!
