TDP--I love the last photo. They just look like they are watching some game at the local watering hole and just having a blast. I think one more layer of wash and then they'll be perfect. I think the teeth were just photographing too white, even though without a flash I bet they're pretty brown.
Sixx--I don't have any patterns. What I do is place the body on top of a paper towel, and then make an outline of the body. With a different colored pen, I then create a pattern, making sure that the pattern goes beyond the outline of the body. For reference, take a look at a simple shirt, and see where the seam lines are. Notice how the sleeve is just a simple shape folded in half. Just deconstruct it in your head and redraw it on the paper towel...
Plus you have the Sideshow General Ursus--you can remove his armor and retrace his shirt on a paper towel. You should also try on his purple outfit on the other bodies and you can gauge to see if it will fit or not. I bet they'll fit most figures since the pants are pretty baggy.
