Meh, I forgot to link this article from Kotaku (phew, "just" few months ago), but it contains so many great artworks of my friends from CD Projekt RED and I have to share it with you.
Of course, you can also find there few of my concepts. :)
The Art of Witcher 3
Also, I want to share with you two pics from Blood and Wine - final Witcher 3 expansion. As you can guess, I had a pleasure to work hardly on many concept designs for this project, including elven palace from first screenshot. :)
Hope you like it, personally I can't wait for the premiere. :)
