Nice, With gradient maps and photoadjustments, you don't want them to make drastic changes to the images color(my opinion and experience) the best results come when they do it subtlely. try lowering the ocup on the gradient map some, might make it seem alittle bit more real. IMO
The first one had a gradient map overlay with 25% opacity, this one is 17% I was originally going to go with 10, but I didn't think it was strong enough
nice magnum your getting it. I would say change some colors on the background and make it near the colors from the army guy next time magnum. keep it up
