Interesting update... a couple I honestly don't really like, but that's just a matter of opinion. Not bad work at all.
Vader Droid - I'm not sure what to think of this, it's weird... and not something I really think looks realistic. It's just... I don't know.
Dug - I like the scarring. It's maybe a bit thick and too red, but it's a great idea and pretty well done. I might tone it down a bit, it kind of likes he got in a catsup fight!
Trandoshan - Blurry pic, so I can't really make out the details like I wish. He looks a little thin, but that could be just me. It's a good idea though, I like armored lizards.
Toydarian - Just maybe a bit too much scarring. Other than that, I love this. He really has an all new look to him, and doesn't look like Watto. Love the metal leg, and the helmet looks great. Best of the bunch.
