I was finishing up my Onar last night when it occurred to me that it might be cool to paint some scars on those massive arms. I've never done anything like that so I looked at a few tutorials, but they were all for light human skin and also a bit exaggerated for my taste. I'm looking for something quite subtle but still easily recognisable as a scar – I don't want people to see him and ask why someone drew on his arms with a sharpie, which is what I'm afraid will be the result if I just try to wing it. I'm also not sure what colours to use with is grey-green skin (I used a more or less 50/50 mix of Celestra Grey and Death World Forest for the base tone). My first idea was to use a lighter colour for the scar and then shade around it, but I have no idea if that would work at all.
So, any advice on painting convincing, non-cartoonish scars on grey-green skin?
PS. Here he is in his nearly finished state. I still need to do the eyes and a few touch-ups here and there.
