Boy, those ears are a Kelley Jones drawing come to life. It's kinda scary.
I like the leathery look of the gloves, cape and cowl (the expression could be better, but I like the way it sits over the cape attachment). Don't really care for the boots or the suit material. The pouch belt is good, but could still use a re-design.
You're right about Zorro being an influence on Batman's design, but it's limited in effect. Kane and Finger drew from a number of pop culture references (as well as their own ideas) for what 'the Bat-Man' was to look like. Rather than appearance alone, Zorro's characterization contributed to Batman.
I get your point about flexibility, but Batman had a greater range of movement in the Begins than any of the other films. It's the lightest and most flexible suit yet. I think one of the reasons they continue to go with the rubber suit, is to convey the fact that Batman is wearing body armor. It could be accomplished with other materials, but I guess they feel that works best. For what it's worth, there's talk of the suit being of a lighter material for the sequel.
