Quick tip - Wraithbone

A friend of mine is working on a Eldar space hunk board and emailed me for help on making Eldar looking terrain. Looking at some of the picture this is what came up with for a quick way to make Wraithbone pillars. It seemed a good way to visualize the shape. It very much reminds me of the old 'how to draw a X' articles that used to be in the back of comic books. Before comic books became cool (yes I read them way back then).
