Once I had a general sense of the characters, I moved on to creating rough concepts of the packages, demonstrating the environments and positioning of the text elements. In this instance while the theme of each is the same, the composition of the illustrations changed quite a bit in the final versions, giving a greater sense of unity and consistency (see above).
Working in Adobe Illustrator allows me to change and refine the colour scheme in a snap. I like to present a few different options because colour can impact how a design is perceived. It might also give the work a different angle or added depth. For Darkstar I presented three main colour combinations (also above) and I'm very happy with the final choice!
