That looks really awesome!
Two points that I personally do not appreciate though, if you allow me to remark, are the big wind plates (don´t know the correct Eglish term) beside the smoke box. They do not look the usual way and I feel only a few of the Kriegslokomotiven had these at all. The other are the national markings, because the engines were never owned by the military even though in Wehrmacht service, they remained Reichsbahn and should therefore bear their serial number instead. Please don´t consider thi an offence, I just want to add a bit of history.
