Tree making and West end scenery

I have worked on the scenery for my west end of the layout because simply that part of the layout has no scenery whatsoever.  I put in the ballast last week and that helped but it needed alot more.  This area is only about 12" inches wide and 4 feet long but I want it to be more rural than my industrial switching area.  This area also has the "hole in the wall" that leads to hidden staging.  So its not easily done.  I wanted to hide the hole in the wall so it will not be visible.  I also have an overpass in this same general area.  I had two overpasses but settled on one so that I could put some trees in to hide the rest of the area.  My sub-road bed is plywood so planting trees would be challenging.  I used some 1/2" blue foam board to give the area some height and to also plant trees in.  Here's my progress:

Background trees have been painted and foam shaped, painted and installed.

Another view of the area.

Initial coat of scenery.  Background trees have been touched up with more paint.

This area with have the bridge span and foundation.  Need to paint the stud in the wall a dark color!

Tree planting is off to a good start.  Since  The little ridge is only a few inches from the track, I had to choose tall skinny trees.  I push in the foam with a Philips screwdriver and insert the tree. 

From a distance.  I have plenty of holes to fill and bushes to add.  Use the smaller trees and plant them in the empty spaces at the top.  Gives you lots of variety and the look of trees behind the foreground trees.

Almost done shot.  The glue bottle is holding bushes against an area near the "hole in the wall".

A track view. The white paper towels protect my ballast from paint, glue and scenery.

VC #3 poses for a shot near the woods.  In my hasty work, I forgot that I was going to send a wood chip tube across the tracks.  Might have to send it the other way now.
