ILLUSTRATION AGE 
Great job! I have done a lot of this type of work, mostly painting on site. A lot of stuff now is printed and then applied. I am curious if this was done that way or, actually painted on the wall and floors. I checked out his website and couldn’t tell…I am assuming most if not all is printed but some, like the wall could be painted directly. His site takes a while to load but worth the wait…some stunning work there.
Well, I think that the floor it’s printed, just like the display’s. Because a floor can easily damage. But I’m not sure about the wall at the picture above, because there’s no close-up of the project. I also think this is great work, printed / painted.
By the way, nice work you have. :)
