Showcasing your portfolio is really important in the process of job hunting, I don't believe that is all about your education but what work did you worked on or were part on. Many things that we share to our next employer totally defines your first impression as a whole.
I really enjoy to see the work of imaginative artists that come up top notch pieces showing different worlds. That really makes you think about the stories of behind these characters and places, which I think is the whole purpose of an illustration.
Here you can see the impressive work of Estonian artist Kuldar Leement. He's super imaginative and talented! But these are only a handful of his pieces. For more of it, please visit his portfolio at DeviantART. I hope you like it. Cheers! ;)
