Some fine modelling there Mr Castle, I especially like the growth along the banks.
If I may be so bold, the photo of 6023 on the Red Dragon is very much Nevardish (refer earlier discussion), with a Studio like sharpness i.e. the recent phenomenon of too much quality?
An interesting photographic challenge might be to try displaying the slightest trace of blurred motion, as one would get from a camera shutter speed not quite fast enough to handle a confined location like this. Perhaps just a little bit of unsteadiness around the smokebox, separating it from pin-sharpness of the track and surroundings.
I'm not sure that the physics of moving the loco marginally during a slow exposure, would create the right effect, it being so close to the camera. But if this could be made to work, rather than fudging it via software, I'd be delighted and regard it as a fine achievement with such a splendid set piece.
