Something to keep in mind, as well, is that at a "global" level, only the larger "nooks and crannies" will be noticable. Secondly, if you could give us an idea of your current wil ur process someone (Waldronate in particular) might be able to offer advice/suggestions that will help you get closer to what you are envisioning. Lastly, for a first map/post, I will echo what Peter said, well done so far.
