Hi Foxkid
I have given your train a short run and I am quite impressed with your work... the chuff, runnning and whistle sounds really brought the steam loco to life! It looks very realistic when running it with a route set in the BR days.
However I agree with eezypeazy that the cab does look very pixelated with BVE 4 particularly with full screen mode. You should really try to obtain a picture in a higher resolution than the current one- it will definately look much better.
Regarding the cylinder chuff sounds, there seem to be a long delay between each chuff. In real life, each chuff is heard per revolution of the wheel so therefore the chuff is heard more often.
I may be wrong, but due to the nature of steam engines, I dont think you can change the viewpoint without making more transparent regions (which means some levers and guages will need to be erased). You can change the x,y location for the driver's seat, but this means that the whole train will be shifted to the right (more like placing the train on the adjacent track) which will make it seem unrealistic.
Thats my feedback for the Mallard. Hope you will take my suggestions on board.
In case you dont play BVE4 (as the trains thats you showed last year were in BVE2), this is what the cab looks like with BVE 4- very pixellated.
