The style and shape of a water feature should always be dictated by the surrounding grade and landscape. Perhaps a very large boulder with two or three 2" cores poring water out in a pondless scenario would work also. It would definitely also give you more noise, which is really what people want. You are going to do well though, your build fundamentals seem sound and you are willing to learn from others which is a big plus for you. Keep experimenting and constantly trying to make them look more natural. You will do fine.
