That's a hair, not a scratch. My lightbox has not been used in a while; it's still rather dusty.
With Grant, I tried to make him as soldier like as possible, He has USMC camo, complete with the standard black knee-pads and boots and dark green khaki webbing. The shirt was done with a light brown Humbrol paint with a brown wash followed by further highlight to bring the colour back out.
That isn't TCR (still haven't got it) instead it's a mix of red/brown ink with some clear gloss thrown in. For Mad-dgo, considering the feedback I got from Mjolnir, I added a bit of green to the flesh tone and it came out nice (not too sickly) and a great shade of flesh. I'm trying to experiment with other colours added in as I go on with the others.
Wristy, I used to have a black rim
but I substitued for this after I realised it made my minis look too dark.
