Now this I really like! Why, it would be great in LNWR black or Midland crimson! Or even better, LNWR red like the LNWR Greater Britain 2-2-2-2 locomotive! I know because I've seen pictures of models. If this baby had the same tender from the first one but with LNWR features, that would make it sweet and charming. All the same, fantastic model, Sir!
However, if I made a suggestion or two, it would be making the chimney the same high as the dome, sticking a whistle on top of the cab roof and making the buffers bottle-shaped like the LNWR locomotives. Plus, the steps at the front could be moved back slightly to where the splashers end and handrails on either side going along from the smokebox along the boiler to the firebox as well as some attached to the cabsides and tender would make it a nice touch.
