You could always illusion stackThen you can't enter in through the marquees.
I read on one of the ditch stacking updates on the Habbo blog that they were going to allow you to walk under furniture you normally cant walk under if there was enough head room but I don't think it has been added yet.
I'm going to have to agree on the dining table. You need to change it. Maybe the gothic table? Or the creepy table.
Also, I'd swap out the back seat sofa with an actual limo piece.
Other than that, it looks good!
