I really enjoyed this. I've always loved animated interviews (e.g., Creature Comforts by Peter Lord and David Sproxton aka Aardman). You definitely have very good animation style, both exaggerated and non-exaggerated and both of them work well with each other to convey the emotion given. I notice a lot of animators use this as a gimmick to elicit a laugh, which is fine, but there is a fine line between comical emotion and blatant over-useage to the point where it becomes 'meh, seen it.'
Another nuance that I liked was the 'sniff'. Even though it was in the interview, you incorporated it perfectly and it added to the interviewers character wonderfully. It's these little things (e.g., the rapid eye movements of a character when they comes across something amazing.) that bring a sense of realism to the piece.
This was very well done and I really look forward to seeing more of your work in the future! Kudos and Thank you!
