It does look really good. I particularly like your snow. Now you can start playing with it. Best thing about Bryce is the Undo command! I'd follow the advice above and increase the resolution of the terrain (the Grid popup in terrain editor). This will help with the triangles near the mountain top. If you want the aircraft to be highly reflective, it always helps if there is something interesting to reflect. Maybe another aircraft, flock of birds, different sky. Now its just up to imagination. Could use a little atmosphere. Maybe some BIG elongated spheres around the base of the mountain with a cloud texture. Could make a spiky terrain (spikes in terrain editor), color it simple black or very dark green, and position it under the foreground slope with the spikes polking through. Looks like evergreen forest. Then maybe could raise some fog around the forest. You could make a night scene, with lighted windows in the aircraft. Or import a figure and have a gremlin walking on the wing. Important thing is to play a lot to learn how the tools work. Then when you know what you want something to look like, you will know the right tool to use. Most of all, have FUN!
