Here is a contactsheet of some Poser Jungle plants posing as swamp plants
These took some postwork for shading (for height between leaves) and some other things.
The top ones are 200x200 and the others 400x400.
Seems Steel Rat did these too, though he rendered the default version in a huge size. I'll probably do others to create at least a difference in pose. Mine are lighter and I removed the black spots and added more shadows on the leaves themselves. Mine also have a perspective shadow instead of a full top-down one.
