As Colhad suggest check out your switches. Use the 'straighten track' button and they (switches) will look much better (smoother). You should use 'bumpers' at the end of your spurs but other than those two suggestions not a bad beginning.
I have made this layout in just 1 hour, just checking if the buildings looks good. I think i am goging to make a layout that looks like a shelf switching layout. Just need soms more buildings to make.
I will watch for the turnouts.
I can upload my layout to my website, then everybody can download it. The layout is build in trs2006.
My website is http://trainzbuilders.yourbb.nl/index.php The forum is in dutch but you can klik on downloads en then you can see the page with the content (when it ready).
Neat! Where did you get those shrubs and grasses in that first pic? They are outstanding! Just what I need. Most of those buildings I haven't seen before, either.
