Thanks Mannie- I have been to your gallery and enjoy your work a great deal. Lovely and something to aspire to.
I forgot to mention that some of the plants are from the Mega Pack and I used a lot of lighting tips from GeekatPlay. I'll tell you, lighting is everything.
I am going to have to tweek down the leaves from the tree that are too big in the foreground- or select a finer leaved tree.
The link to full size image in the original post does not work properly- they have it defaulting to 600px in their script - so here is the link to the page, just click on the image for the blow up. http://www.sharecg.com/v/38510/3D-and-2D-Art/Tunnel-Bridge
