I take your point. The diffferent colored rocks are interesting in themselves but are featured too much I think. Although a natural stream will have a mixture of rock types and not one type. I think I will go to my local beach (where I picked the rocks) and collect a number of the same type and swap them in. I will send photo of the result so we can look at before and after.Rob G said:I know it's just a personal opinion, but might I suggest attempting to use one color or shade of the smooth rocks. The multiple colors seems a little distracting, but that's just my take. Overall, I really like it. Thanks for sharing the photo.
