Added a decoration rim around the cap and modified the upper lip.

He looks more aggressive this way.

Also I added a skull decoration to the top of the cap.

Really Orkish ugly :)
Than I continued on little boy.
I added the pants and jacket for the right side, plus some deatils, like a skull emblem on the chest, some more cords and a belt thingie.

On the rear there's still some cleanup to to.

But the pose is really what I wanted.

Then I worked on the body of the big boy, and started with the neck and left arm. Eventhough he will wear a uniform, I think I will leave the arms exposed (I have yet to see an Ork with a long sleve uniform).
