Yes, for a first time attempt, this is good. Many things can be done in many different ways to get what you want. For bow wash, go into your image editing program of choice (PhotoPaint, Photoshop, Painter...whatever) and using a black background and using shades of white and gray, create a top view of your bow wash as you would like it to appear around the shark's fin remembering that the darker grays will have less elevations than the lighter grays. Black is zero elevation and white is the highest elevation. When done, save as "BMP" image (Bryce 5 can accept "jpg"). In the Bryce scene, create a terrain, then go into the terrain editor (the "E" in the wire mesh mode). Make the terrain resolution 512 or better, click "new" in the Editing Tools panel. Then go to the "Pictures" tab and over the leftmost image click "load" and load your bow wash top view from your image editor. Below the leftmost click "copy" and below the middle image click "paste" then "apply". Go back to the "Elevation" tab and use Raise/Lower button to lower the new terrain to where it's just above positive ground level. You may now click "smooth" a couple times. Now in the "terrain canvas" next to the down arrow in the upper right of the canvas frame, to the left, you'll see a little drop down window icon, click this to expose the clipping gradient bracket. Bringing your mouse curser to the lower part of the outside bracket (not inside the gradient itself) slide the clipping bracket up until, in the canvas you see your bow wash surrounded in red (maroon...whatever). Now click the check mark to OK the terrain change and bring you back into the mesh mode screen. You may now position, and resize your bow wash as needed and you can add a material of your choice to it. Happy hunting!
