Just got back from the movie. A couple details to improve this bad boy:
There is a thin blue or black line in the shape of a hexagon INSIDE the back spider.
I'm fairly certain the back of the belt is red.
The black arm and leg bands (Not the lines) looked like rubber (Actually very similar to Cap's Avengers' shoulder details, just in black) and definitely had the appearance of a subtle ridge top and bottom.
Everyone is designing the eyes WAY too thick, they are almost imperceptibly layered, and the "default" size of the eyes seems to be between open and squinty. (In fact, if you start going frame by frame in the trailer, the 4th or 5th frame of the lenses changing is probably right around the default size)
For future reference: The spider appeared to be silk screened directly onto the suit and WAS dimensional likely with a puff ink since it was slightly domed.
This suit MAY just have beaten out the Raimi suit as my favorite after seeing it in action.
