Classic red and gold to match the rest of his collection, I do keep saying it but Games Workshop do make some very nice stuff ! 
Sotek green as a limited accent colour and of course blood oozing from fleshy parts where the mechanical parts meet each other. 
The base was kept simple but a small amount of detail was added, the rusty metal and razor wire will pop once the snow as being adeed. The snow will be added but not by me, I did add a couple of extra bits but I forgot to take another photo. An abandoned guardmans rifle and helmet added a point of interest just to suggest an unseen enemy. 
So that about wraps up this post! So thanks for looking and catch you all soon
Cheers for now Russ
