The pepakura file was released last week or so. You can find it on Forged Reclaimers pepakura page. As far as when the biceps will be completed, probably may or june.
The plan is to sculpt the rest of the undersuit for the torso area and have this act as a cover for the zipper where it joins. In the picture I trimmed off the excess where it expanded past the mold before removing it. It is easier to remove before demolding because the part is thin and flexible. This keeps it uniform and made it a lot easier to trim. I am extremely happy with the results. I will try and paint it up so you can see the details a bit better.
