Approximate? Very good.

I'm really not the one to try and help, except I think you have a good start 
on trees/plants there and you will probably need to move from something 
other than basic primitives and pigments if you actually want realism. 
Although, a lot of faked realism can still be accomplished if you apply the 
textures right, like using image_map or a very convincing color_map.

Since there has been other tree or plant generating things done before, you 
might want to take a look at those. Here's a few:

And this might help, too. It's Gilles Trans explaining how he made one of 
his great works of art (I think they're great) which happens to be about a 
tree:

I'm sure there's more out there.
