I'm a big fan of the font choice and complementary colors, which really help the "handwritten" drawing design to stand out. It looks like someone was doodling, which is a cool effect and not too distracting from the message,
This design makes me think about photographic elements and the complex positioning. Layering is a easy way to create interest. Use dimension and depth to help move the viewers eye around the page and thru elements. Well done.
