Predator Sketch WIP

Was doodling the other evening and found myself drawing a Predator..

then decided to draw another, this time with a screengrab from one of the films as reference.. just roughly blocked out the shape with the reference then filled in the detail from memory. Predators are a cool subject to draw, with dynamic poses and an iconic silhouette they always look bad-ass
This is how it is progressing, might overlay some color on it with watercolor or Photoshop, have yet to decide..
