Malibu High Logo Designs and Demographics

Here are some designs I made for Malibu High. It was a certain challenge for me to think like this - having never done so before. The challenge was to design something kid friendly but also make something adults would wear - I had to stay under 4 colors - and I had to think like the beach. I had many designs - these were the picks. It was difficult to figure out a flow and pattern to them all - In the back of my head I had to think of placement and style - The demographic element to design is very difficult to get the hang of - its either hit or miss - I think these turned out well. I hope they like them.
