Alien Life Form

This one was sort of out there. I wanted a different way of filling in the space that the 22.5 angle took up. I ended up filling it with rounded shapes. The long outer legs of the trident shape at the 45 degree angle was a happy accident. Here I didn't like the way some of the long ends of the shapes protruded into the shape ahead of it so I rounded things off. Fewer spikes this time as well.
