I'm sorry guys but I don't have the time to follow all the forums that I like, I try to answer now to everyone:
@knightkrawler: I know, the colors are too "bright", but I wanted something like that for the adventures I had to play

. The print is in A1 because it has a white border around it, the size is equal to the original board.
@Valnar Nightrunner: great idea, when have the time I promise you make the rooms set modular

@Daedalus: when I did this I wanted different rooms and those of warhammer are beautiful !! I do not know how it fits in the gallery, for me the important thing is to share it with everyone!

Thank you all for your support and advice !!
