So this will give a good idea of the scale of this beast. This strut is the detail of a section of the Terraformer where one of the arms meets the midsection. This was drawn over rough geometry that was used to block out the basic forms. The red things on it represent the scale and positions of Stalkers. There was once a reason for all this detail... but you don't see it in the game anymore.... At least we thought of it!
Love the style, and the detail is impressive. Although not much of a Resistance fan myself, so barely have any knowledge of the subject, I appreciate your art much more than the game itself.
