I am working on redoing the railings (need something that looks higher poly) and decided to make a highpoly and project a normalmap. If you have a 'normal bump' applied to a 'highpoly' mesh, when you project normals, not only will it project the highpoly mesh, it will also project the applied normlamap. Here are my results from this process so far.

Here is the texture used on the hedges, feel free to use.
