I had the recent pleasure of working on a portfolio website for one of the best designers I’ve come across on Dribbble: Peter Voth.
In case you haven’t followed his work yet, he does many great illustrations for Timotheus Magazin, Doctrine and Devotion, and of course, his own insane portfolio. He drew up a great concept based off of illustrator Emir Ayouni, but with his own disciplined approach. The control of colors and line strokes is pretty evident to anyone I’ve shown his work to.
If you do nothing else today, go check out PeterVoth.de and check out his work. Highly recommend.
