Take a look at your desktop (the real one – not the screen ;)) It’s there, whatever you see you can, for instance – scan and start from there.
In this example I will show you how to use stuff from your desktop to get compelling illustration.
So, as I sad – scan something that you found on your desk. In this case it’s mobile phone and pencil. Important: Don’t forget to cover copyrighted words or logos.
Place them into Illustrator (or CorelDraw) and trace it in b&w (2 colors mode. Both Illustrator and CorelDraw –offer built-in tracing feature.)
These “messy” spots and dots are actually very welcomed because we will use them to get some grunge look of the illustration. Place your vectorized stuff around the background.
And after some playing around with dots and spots – voila, the illustration is done!
On the other hand, if you need this illustration for any purposes, why bother going through all this when it can be bought for just 1$ at Shutterstock.com.
