This Iron Man Mark VI was pretty easy overall. I added silver under the armpits to make the suit look a little more layered and just drybrushed all over to bring out the detail in the armor and added some weathering. Then I took those armor shoulder pads, dremmeled them down a bit,thinned out the inside of the pads and armor ridges on the torso where it meets the arm to allow a 90 degree arm raise (perfect repulsor posing angle!)ande poxied them directly to the shoulders for better poseability (they were lame attached to the torso).
Here some pics that show the articulation, This is about as good as articulation you can get when attaching them to the shoulders. The more realistic poseabilty I gained far outweighed the 5% of arm lift I lost (if you rotate the bicep,this small loss doesn't even make a difference). Enjoy!
