Artist Pablo Stanley has made an awesome character illustration library available for free. You can mix and match clothing and hair with ease. Rotate and position the elements in your humaaans however you like. They're like legos made out of flesh... and vectors. Included with the library are background scenic elements that are also interchangeable.
The humaans library is free for commercial and personal use.
