The premiere of Batman vs. Superman is still two years away, but here’s a picture of Ben Affleck as Batman and his Batmobile. In fact, the script is still being written, but working out the look of the superhero is an important development. Every filmmaker’s iteration of the Caped Crusader has been slightly different, and this time around, Batman gets a textured suit with seams that make it appear as if his veins are sticking out. The Batmobile is a futuristic armored sports car as it should be, but this one has wings! Only time will tell if we’ll see it fly. -via Film Drunk

But I don't recognise the veins, they're just (thick) seams and fabric creases (near the armpit) to me. Take a look at this lightened picture for better detail.
