I started on Ferdinand in 2014. We had a few style guide pages put together that were really helpful, including a proportion break-down indicating we would follow a "big-small-tiny" theme. We had a couple of rough character designs done, but not a full line-up, so I couldn't key off any specific character motifs. There was an early draft of the script I could reference, but no idea as to the era/time, just location... "Ronda, Spain". These were my very first pencil sketches.
