Spent all day figuring out how make good looking low poly trees. I tried out a dozen different methods until finally making something close to what I want; i.e. good silhouette, looks good from any angle, and low tris. This one is 1700 tris, but I think I can definitely get it down to at least 1000 and get the tree texture to look less repeating. Also should be able to get trees that have a decent variety of shapes with this method.
