I find fantastic when Illustrators come up with great concept art, depicting the future in their own visions, like the amazing work of Michal Lisowski, a Polish artist that's done some amazing works for big companies.
In his personal site and at his portfolios you may find many more of his pieces, which are stunning. Don't think twice before visiting it, because it will be worth the click. I really hope you enjoy these, and don't forget to tell us if you know any more artists like Michal. Cheers! ;)
