I animate graphic designer's illustrations for a living and always wanted to be able to create my own illustrations. I think this is a great starting point. The word Loud spoke to me the most. I have two rough concepts:
1, Focus on individual icons that represent loud.
2, I have never been to Vegas but have always had the association of it being a very loud place so I thought I'd create a small "Vegas" world where all the individual icons symbolize how loud it is (light,planes, casinos,cars etc.).
