Thanks for the feedback Mike and I am glad you like the concepts.

I have been working on completing the arm section and have about half of it done. It looks really basic but it is actually very complicated. I have broken the pieces of one arm apart so that you can see the components that make up the construction. - Oh how I wish my model was not so organic as pipes and squares are so much easier to model. I am sure it will be worth it in the end.

Gotta hurry and finish the model so I can rig and texture it!!! Fast running outta time.
