I work as a freelance illustrator for over 3 years. The first time I knew illustration was when I was in the university in the last year in China. At that time, I total had no idea what is an illustration. I merely had an interest in it.Then, I searched relevant information online and I found watercolor is a nice material. Also, I found there is a good website which is called lofter. Many high skill illustrators post them drawing on it.
