I like the design of the character. Really, really awesome! And there are elements of the New 52 suit I like that you have here (the high collar, some of the seam lines on the suit, the longer sleeves). This is a great design. I look forward to seeing the rest of the League hopefully? I'm sure you've got a great take on Barry, Hal, and AC!
Oh, I like this. It's such a subtle variation on the current Jim Lee armor, but those little tweaks you've made make it look so much better. The general lines of the belt look clean and streamlined, and the yellow really makes it pop. The red piping on the knees and forearms draws the eye without distracting, and attaching the cape to the shield makes a snappy visual SENSE.
