That's not concept art, that's the actual suit effects. The big diamonds in the center of the chests are there to bring back some design from the original Mighty Morphin' Rangers. The movie is supposed to be a reboot of the original team.

Yeah, I knew they were rebooting the original team, it just doesn't look like the original pattern without the other two half-diamonds at either side :/
