Blocking out compositions quickly with Custom Shapes

Awesome environment concept artist Sparth posted a helpful tip to speed up composing your works. Basically, convert shapes that you make into vector form, and then you can warp them however you like to compose your image. For instance, sand dunes you create can be warped to fit your scene's perspective. Also you can create lots of detailed elements quite quickly (i.e. building ramparts, etc).
