I've been working on the design for Theseus's armour first, as I love hard-surface design. Below are some sketches to get things going. I find my Pentel Brushpen is great for loose working; if you work small you can generate ideas quickly, and happy accidents abound. I then scan them and draw into them in Photoshop. Proportions are a bit off, but at this stage I'm more interested in finding a design direction.
