WVC Vacation Bible School brand

Working on the brand for our churches VBS program. This year is a time travel theme. I want to have more of a crazy contraption with a bit of a retro vibe rather than overly futuristic style. I am excited for this entire project that will be packed with fun characters (Cliff and BIff), time machine elements, Bible scenes and an activity book to create over this month. They asked for it all as vector, so I am challenging myself to try some new techniques with Adobe Illustrator.
