I'm still waiting for you to point out specifics. I'll tell you some of the differences I've noticed.
1. The mask opens up (in addition to having a metallic look to it)
2. Reptile's tongue now being present as an in-game weapon adds to his look like never before
3. Bones are on his V-neck now and arranged in a tribal-like fashion
4. The hood has a silver material stretched over the black, meaning it is double layered. If you pause the reveal trailer at 1:03, you can also see there are line patterns on the side of it
5. The back loin cloth is shorter this time around
Those are just a few that jumped right out at me. Why don't you name some actual specifics instead of saying "loin cloth, mask, etc." AKA things that are pretty much staples in EVERY ninja's costume in Mortal Kombat?
