Can you help me? (It's important!)

Hi guys, I’m working on a school project where I have to make a “Themed Continent”, I was thinking it would be really cool to make a model of the island in Terragen 2. I’d need a heightfield, but I don’t really know how to make one, so I’d appreciate it if someone could whip one up.

The continent’s an islnad in the Pacific, shaped like the front of a drumset. The bass drum has mountain Ranges in the bottom, And there’s a large lake (Think Great Lakes) towards the side, as you can see in the picture. There’s also a cymbal island. Please include all the physical features written on the picture. Oh and in the picture Sabian Lake needs to be switched with Mount Portnoy.



Why not use the sculpt tools in blender, you’ll have more control over the shape of the island. Then you can use the subdivide fractal and textured brushes for noise.
