Don't do yourself down Rob! My excuse is a misspent youth of game workshop figure painting, they're ostensibly 28mm compared to our 120mm, painting eyes on em was a bitch!
looking at you're figures rob nothing wrong with the neatness and technique, I think a slightly different colour pallet could make them really pop.
I've seen mig has a flesh tones set out which I'm going to buy. I've got some figures for Andy which will be getting this treatment so I'll try and do a run down and step by step then.
I'm very much of the layering school, building up gradually with thin layers, I don't use washes or inks on my figures faces at least, but it's something I've been meaning to look into.
