Yeah, the size isnt really an issue, but the uniformity is to some extent. There should be a lot more variation in shape and a bit of variation in size (not too much, old growth forest tends to kill off most of the non-moss/fungus vegetation on the forest floor, blocks out all the light) and some dead trees too. Still, EB isn't exactly swimming in 3D artist, and it would make loading times and battle speed even slower.
