All of the artwork we're currently exhibiting and that is available for purchase is made completely digitally. I've worked with some of these guys and what they can do with a Wacom in Photoshop... Pfff, it's amazing
Metropolis by the way is an original piece of art from Kuciara himself and not from a game or film or other. The last commercial thing Maciej worked on in the video game space was The Last of Us from Naughty Dog Inc. as lead concept artist.
Shipping a piece like this to the US would probably be around US 150 dollars.
