The first one the pattern tile too much. The second one with RobA's script is much nicer, now the floor look good. The white areas are very white though although I know its for printing purposes. On the last one, I like the idea of a "rock" pattern in the walls, but the fade to white suddenly draws attention to the walls instead of the floor, so get rid of that ... and then work a bit more on the rock texture and you might have a winner. But as they stand now - nr. 2 is the winner
