The image on top is my sketchup version of the picture on the bottom, it is incomplete, but it's taking me a while, so I thought I'd post my progress. To make this I just used the rectangle tool to draw the ground and wall, also to make the blocks. I only used the colors that sketchup had, so the colors don't really match. To make the trees I just stuck a bunch of spheres together. For the raised ground I drew the outline with the pencil, then used the push pull tool.
