I honestly don't know much about The Flash, but I was inspired to create a poster for a Flash movie. A lot of people on here seem to think Charlie Hunnam would be a good candidate for the role so I chose him.
I gave his costume a bit of an updated, real-world feel with light weight flexible armor. I lost the bolts on the ears as they seem a bit silly to me. (Do they serve a purpose? I don't know, like I said, I don't know much about him).
I used images from Daredevil, Captain America and some racing body armor tacked on.
