You know that there's a shortage of on these forums? Northwestern worlds-like western Washington, western Oregon, or British Columbia. (A small town in the lush forests there would be really cool.)
Whatever trees would be found in the area you're basing it off of-like instead of just oak, maybe throw in some pines and birches if it's back east, or maybe a bunch of redwoods if it's in the northwest-whatever look you're going for should decide what trees to use.
Meh-whenever there aren't many people commenting on the pictures I post of any of my worlds, I just go ahead and continue building, asking for advice once I've built something-hasn't failed me in the past!
