After you make your next round of updates for this, is there any chance you could take those screenshots in an exterior location? I want to see what this skin would look like if it was well lit.
By the way, looking at the robes in the initial post, I think black robes over the Ubese Armor might be a better starting point for you rather than the Revan Robes. For example, here's what Dak Drexl achieved with a Ubese armor and robe combination.
Granted, you'd have to use a hooded robes but that shouldn't be an issue.
One last thing, no matter which robes you wind up using - you're probably going to have to do some major work on the forearms - beyond just skinning. Again in the original picture, those hands and forearms are encased with some serious thick armor plates. They're pretty close to Boba Fett's in shape if not in color.
