Nice update Darth Ennis...
-The Katarn figure is interesting and seems pretty accurate but the head is very Obi-Wan, that's my only thought on it that I think I would change. The Hasbro Katarn head isn't bad, it just lacks detail in paint aps that it needs to really bring out the likeness I think. If you could track a cast down perhaps, or a cheap Katarn figure (less likely) it would be cool to use that head and paint it up I think. The rest of the work looks pretty sharp though... You could add more accessories for all his gear, or if you got the Katarn figure itself it comes with 2 of his weapons (the Bryar's a good bit more accurate than Cobra Commander's pistol, so it might be worth picking it up?). Overall very cool though, and Katarn figures are in short supply in customizing I think. Given the character's popularity and pretty extensive background with different outfits and "looks" and all.
-Smuggler Lando... I have never been too big on getting a Smuggler Lando myself, but I think you pulled off a pretty cool figure that looks like he raided Han's closet. The collar looks accurate, everything looks nice... My thought though is that, and I may be one of the only ones here, I would have used the Cantina sculpt because it's a little bulkier and Billy Dee Williams always looked a little bigger than Harrison Ford's body size in ANH. Ford was smaller in 76 when the film was being made than he was in 79 when ESB was wrapping up it seemed, so the ANH sculpt of the VOTC figure that's really accurate to a thin Ford doesn't necessarilly match up to Billy Dee's build as I can picture it. I just see him having a little more bulk to him. Since you see him from only the waist up you could also take some creative license with the holster area if you wanted to change him up I think, but only if you wanted to set it off from Solo a bit more.
-Dyed Fett... That's pretty neat the way it came out but I agree it is indeed missing something. A repaint of the gauntlets is where I'd start, and I'd cover the emblems of Fett's armor if this isn't supposed to be him particularly. Now beyond that you could do away with the cape maybe and give him either a more full one (not so tattered?), paint some new design on the armor perhaps, and just maybe clean the figure up a bit (less battered/war torn looking). And give him a new custom gun. cut some bits up, make him a new blaster all his own. Could be pretty cool I think and would set the figure off from resembling Fett so much.
