Thanks for the share, Tamer and thanks for your comments everybody!
Since Tessek is going to take me a bit to finish off, I thought I'd share a little of my process on the upgrades I'm doing. I'm sort of approaching them like homework. I'm trying to complete them using materials I have on hand while focusing on a particular skill I hope to improve on each one.
With Hammerhead, I really tried to focus on hiding joints. Labria was face paint and Tessek will be improving my soft goods skills. I originally intended to use that vintage skirt but as I was looking at the reference two things stood out that I wanted to incorporate into the figure. The costume has a lot of volume in the skirt and the fabric is used as the lining of the cape. The lined cape is something Hasbro did with the last two Bespin Lando's and was something I wanted to try to incorporate.
I found enough fabric to construct a new skirt and cape lining. The previous photo was just a test fit. I'm now recoloring the fabric to match the figure. It may be hard to tell in this pic but what was stark white will be "antique" white which is closer to the color of the vintage piece and matches the limbs.
I'm also trying to match the aesthetics of the nouveau vintage styling so I took my inspiration from one of the more recent Leia figures and the Bib Fortuna I completed last year.
So even though I purchased that skirt years ago to incorporate into this custom, it just didn't fit with where Tessek is going now. Well, that's enough typing. I have a cape to build...
