This looks great Pete.
End-on views aren't often explored on layouts, perhaps because many people feel that scenic breaks are a must. I have discovered the pleasures of end-on viewing with a couple of my layouts though, the depth does add realism. Taking photos from that angle can be more difficult, as the camera cannot be tricked to disregard the chasm along the front in the way that your mind can! But never mind - layouts aren't built for photos after all.
I have to say, 2mm stock has become quite detailed of late
