I really really like the third take, but I like the top from take 2. The shoulders are a bit weird with that opening, but I really like the front chest "plating" and the straps leading tho the back, but I like the lower half of take 3. Great designs all around.
I like the first and third one best. Nice studies overall. I especially like the simplicity of the first one and the asymmetrical gl symbol on the third. Also the third one has a nice armed forces feel and John was a marine so it makes sense. My only minor critique is the gl symbol on the leg guards. I'm just a one logo kind of guy. But regardless this is stellar work!
