e)  This was fun.  I originally made a spring scene, with more green leaves, 
but my 7 year old thought the orange/brown ground I had looked more like fall.  
So I tried it, and it worked pretty good.  I would have liked a more random pattern
to the trees, but this was the one that gave the impression of "forest" the best.
I like it for 497 bytes.
