How many rendered versions of a plan can I possibly have?

The saga continues. I've been working on a rendering style for my the plan view for the camps. I started with Camp 1. It's difficult because the entire park is completely covered by a dense canopy of second growth redwoods. I mean, in a real plan view you wouldn't see ANYTHING on the ground plane. So I've been working to develop a rendering that both shows that there's a dense canopy throughout, but also shows what's happening on the ground plane.

Here's my first attempt:

This first attempt is ugly, ugly and ugly. It doesn't really show the new plan well and it looks like something you might see on a fail blog. So I kept at it... tried multiple things and it just sucked. So I took the aerial into Illustrator, drew a tree shape using the pencil tool, used a clipping mask to clip a tree shape from the aerial photo. I then brought that into Photoshop and copied and pasted different sized/rotated versions of that about a billion times to get to this point of coverage. I also used color adjustment layers after bringing in the "vector smart object" line work for the plan from Illustrator. So here's the second attempt: 

I showed it to a friend who is not in Landscape Architecture and she said that the ground plane within the camp looked like it was scrub/shrub. Having that insight was helpful.. because I didn't see it that way. So I took her comments and have not come to this point (it's actually version 6 or 7): 

I'm a lot happier with it now, but I think I need to add some texture or detail to the water to give it some depth. Now, on to camps 2 and 3.
