Before you rush into the run cycle, work on your standing some more. The new design is superior, but there is some more cleaning up you can do. In general, the lines are jagged and not smooth. The gun is looking fantastic, it's very smooth. I would love to see the rest of Rambo given the same amount of care.
But work on the basics before you rush into animation. Also, his anatomy is mostly fine, except his right foot (our left) needs to point towards the viewer, not at a profile. The legs themselves are also kind of big and too separated.
I noticed his pose is similar to the Contra guy.
