For my Production Bible, I drew some more model sheets for the costume/colour changes for my characters over the seasons.
I've changed the colours for "Autumn" slightly and experimented with changing the Spirit's colour for each season. I think "Winter" and "Summer" came out well but I'll try out some extra colour schemes to see what works best between characters and against the background too.

I also coloured in a couple of my sketches as character pictures for my production bible. I particularly like giving Amber primary colours and having the Spirit as the only character who is green and therefore in sync with nature.
