I'm going to be a little more nitpicky than Paul... the alignment of those steps is a little to the 'right', it needs to move to the 'left' and fall in line with the door part. Steps normally fall inline with the door rather than being offset like yours are.
Nice! I like the 1st one on 2nd row (when stairs back in line ans JE..A..N sorted).
I'd say the 2nd business card, with the bricks dotted around, looks a bit cluttered and random - if you're going to incorporate the bricks, maybe just having some at the bottom, so don't detract from the logo (but I think 1st ones are better without as if got bricks on the back not really needed front too?).
