Yes, those rivers are much better behaved now. As for other advice - I assume Autorealms only gives one mountain symbol, one hill symbol, and so forth? The overall style is supposed to be hand- drawn, but the repeated symbols sit there whispering "but I'm really generated!" If you don't get a choice then just shrug and move on - it still gives you pretty good looking output .

If you're dissatisfied with the way the trees work now, take a look at Ramah's TreeThing.
