Ork Objectives (Pt III)

I finished my first objective, quite happy with it as well. I used the turquoise of my army to tie it into them.

This one is almost done, I have to do some work on the helmet and then do the spilt ale.

And this last bit, I'm not sure about so far. The yellow was an attempt to show the previous colour and the bullseye is odd because no ork would do it straight. I have so far just washed it with devlan mud but I'm not sure it looks any good. :/

What do you think?
