Everyone has made great customes of what Blake might look like if the Nolan universe continued but no one has done the most basic and what I believe Nolan himself would actually have Blake look like. He would just wear batman's old suit! Because he is not Robin (why would he be called by his FIRST NAME, lol and wear an "R" like a name tag or something) and he wouldn't go by Nightwing because he's the new BATMAN! Like Terry McGinnus taking up the mantle once batman couldn't, he was just called "BATMAN." :P
I did one very similar, though I adjusted the paint and changed the cape. Definitely the direction Blake would have gone. I commend your work here.
That was pretty symbolic. And, adds to the idea that Blake becomes the new Batman.
nice
