I'm not sure I can pin point any one thing that inspired West. It's a product of everything I love and admire in films, books, games, relationships and am intrigued by in day to day life.
Films by Studio Ghibli heavily inspired the pace and asthetic. Others like The Prince Of Egypt inspired the vibe. Games like Skyrim and the Assassins Creed series taught me how to move things along and tie things up in the end, and the practise of completing those games through problem solving was especially helpful when devising my own plot.
Spending a lot of time in (relatively) remote places by the sea, in the woods, and in the mountains was a strong source of inspiration. I'm forever trying to bottle that sense of smallness and inject it into what I do. I also walk a lot, exploring caves and rivers and anything else I find, so I've come across some really strange things and gotten into a lot of trouble, which is always amusing to work into the comic one way or another.
West is inspired by old tool kits, colourful rugs, and those crunchy, salty boat ropes as thick as your arm that wash up on the beach and get tangled in weed. I see reflections of people I know in the characters-- my family and friends-- and continually collect memories to drop in when a little something more. It is a manifestation of everything I am-- as I am right now-- and it's kind of scary.
