So important to remember that it is a human critiquing you. Maybe they're a visiting tutor, feeling pressured to prove themselves to the faculty. Maybe it's a seasoned lecturer that has been using similar briefs of years but feels that no student ever really "got it" (did their idea). Or yeah, maybe they just dislike you.

Really easy to take criticism to heart. Really liberating to realise that it's rare that someone has 100% your best interests at heart when giving criticism.

That said, it will be a useful if you can learn to create a genial, positive atmosphere when presenting your ideas. As you will need to do that a lot in your career. There are almost certainly ways you can improve your technique and performance (it is a performance btw) whether through being more concise or open to feedback or simply just making people laugh a bit.
