Thanks for the suggestions everyone. Here's a little bit of progress with much lower quality render this time. All of these were rendered at 0.4 detail, 5AA and model detail set to medium, so I would expect the final images to look much better.
Similar point of view to the original (ignore the missing trees in the background, limited here for speed)

Next steps are to continue to work on the underbrush, and then figure out a good way to create a camera path. First attempt I think I will try with Terranim but with all the trees I might just have to do it within TG2 ugh.
