This is Zack from the 5th episode! Probably one of the many favorites on which me and my team worked on! The posing layout team is a huge one, so to increase efficiency, we were all sorted into smaller ones and were assigned to different episodes, so that we can stay on track with the deadlines.
Of what I'm really proud of, in Season 1 anyways, is that I was granted creative freedom to do some of Zack's expressions. The disgusted ones, in particular, as well as his bluffs to lie his arse off. At that time the SPUs were lacking, and rough animations weren't there, so I had to improvise and basically use a face mirror to accommodate on what was on the storyboards. It was a weird and fun experience, and it turned out great in the end!
