It just occurred to me that despite having marvelled at this creation for so long, I still haven't actually added to my fav list... time I put this straight :)
To be perfectly honest, I used your design as a reference for my own 6-wide Routemaster model. I do believe you have done a great job with this one... keep it up mate ;)
P.S.: This one is so good it even gets copied (although I might be wrong, but then again even the pics are the same...!?):
