Digital Illustrator Needed for custom vector Designs & Design Ideas

Hi everyone,

We are currently looking for some new designs for a colour changing umbrella range.

We currently sell cityscapes but we would like to expend the range and need some quirky artwork that would fit the following criteria;

- The artwork should be white when the umbrella is dry, the colours appear when it gets wet. (so two artwork are required, the white version and the coloured version)

- The maximum amount of colours is 5

- The theme is open, we are open to every idea

- The artwork should be produced on Adobe Illustrator

- The design should cover 4 or 5 panels on the umbrella (out of 8 total panels)
