So heres the Foundry Rogue Trooper ive been promising.
Fantastic paint job and colour scheme!
I am with Commader Vyper on the sculpt though. I have that figure at home sitting with my primed Bronze Age GIs and he really looks gawky. His head is huge. The same applies to the Venus Bluegenes figure sculpted (like many of the later Foundry 2000ad figures) by Tim Prow I think.
I intend to paint my Foundry GIs when I get around to painting the others but like yourself, it will be for a sense of completeness more than anything else.
I love the skin tone in particular though.
Looks absolutely excellent! One thing, though, that gun casing - I thought it was some kind of futuristic plastic assembly, not wood (as yours appears)?
The GI rifle casing has AFAIK always been a brownish colour, sometimes with a bit of olive drab or similar in it in it. It commonly has a vertical striping effect not unlike wood. I never felt that it was intended to represent wood however.
The helmet has always been green I think and the backpacks and leg packs varied in colour between the helmet green and the rifle brown depending on who did the colouring as far as I remember.

The video game version made Rogue look a little more like Friday: a little more militaristic and a little less super-hero-y. His gun and equipment vary from green to grey/green. There is very little brown in his palette.

A bit like most 2000ad uniform elements (Judge Dredds knee and elbow pads spring to mind) the colours are not really set in stone. Anything from brown through grey to green for Rogues equipment seems legitimate to me.
I might of course be totally wrong, since I´ve only read the b&w comics so far.
I can still remember the day when I was a kid that I finally saw a picture of Rogue Trooper in colour. I remember being completely shocked that he was
