Give your project a unique and personal touch by illustrating the most important subjects. An illustration is an important eyecatcher on your page. It attracks the attention of your visitor. The visual design of your project is pretty crucial, the ultimate goal is to trigger a reaction like : "Wow, this looks awesome!". Although the technical side of things is also important (was your brochure printed well, is your website being coded correctly) people always looks at the design first and then the technical implementation. It's rarely the other way around...
