Very nice! You definitely are more talented at painting than I am. You were able to actually get the gray to stand out, which I don't really think I did. I plan on leaving more gray in the future.
The one recommendation I would have is to stipple the colors on a little more. If you look at the below picture you can see that the brown and green fill up more of the uniform than you have. I am not criticizing your work, which I feel is superior than mine, just tossing it out there.
