Yeah less grass would be nice and the grass that u leave, need to randomize it more, make it look natural, and maybe once or twice, put a tile of swamp or one of those green bubble looking thingys. Maybe add a stream crossing one of the pathways or something. and for the treehouse, out a treehouse there so that it looks right then if u want the tree tip to look golden, just put a golden gif on the top of it that looks like a treetop. The top of that one building there doesn't need to be as many of those round wooden thingys, but other than that it looks fine.
