It's a nice idea, but it's a bit unfeasible with this one. This picture makes use of a number of tricks that make it only look good from this angle (I didn't add any trees beyond the edges of the camera's borders), and there is no sort of structure behind it; of course, I could always add those props, but adding too much could affect performance. Plus, I actually rendered this twice, the second to fix a few errors and to add a few more men to the image (all unnecessary elements were removed in this second render).
