Lightsaber looks cool, but hella impractical. The point of a crossguard is to protect the wielder's hand. You obviously can't have the blades touching the hand, but the metal part provides no protection when an opponent's blade slides down, since it'll just be cut through. The improvements in this thread all fix this issue and look just as cool.
Also, it's a bit weird how they're still using X-Wings, TIE Fighters, Stormtrooper armor, etc. in the future. I did like the new speeder bike; it's very Star Wars-y and the odd shape reminds me of how they came up with bizarre shapes for ships in the original trilogy (The Millennium Falcon is a burger with a pickle next to it).
