All looks so much better now you have added the grass and ballast.Still not sure about the change of sidings to R1 loop though, but can understand how it makes life easier than climbing over the decking to get at it for shunting. There would appear to have been some scope for sidings at tje front left before the runnel? The area where the loop is could then have been reserved for a township? But the way you have done things all is up for revision with ease should you wish to going forwards.
Glad you have used electrical trunking for wire runs, makes life so much easier.
