I'm not sure who the almighty judge was who "dissed" your little diesel, but may his socks rot! It looks fine, represents exactly the sort of little shunter many small industries employed, and if it isn't 100% faithfully prototypical so what? Locos that look right and run well are fit to be seen on a layout.
I think it was in the April 1964 RM that the late David Lloyd described his Irish NG layout "Augher Valley", and for this 15-y-o it ticked a great number of boxes. I am certain he noted the impressive scenic effects were by "my gifted friend Peter Midwinter" and while that layout is long gone, it is evident that you are still well up to the task!
Thanks for the comments. The Augher Valley was here with us in Wales until about 2008 when the barn was flooded and most of it was destroyed. There are still a couple of boards mainly the station that are still in the old workshop. I just do not have the heart to get rid of them . By the way at the time the layout was built in 1960/62 I was 13/14 years of age.
