Absolutely AMAZING. I visited the Petronas Towers this summer and have had this idea on the back burner for a while now. In the basement of the Petronas Towers (KLCC as they call it in Malaysia) is a Toys R Us Toy Store, and in it there is a 6 foot tall Lego KLCC. I can't imagine how much it must cost to build one 6ft tall, but yours is as true to form as theirs, but cost a fraction as much.
KUDOS to ya !!! Keep up the good work.
