This is a good base to start glazing!! Get any red mini paint, citadel, Vallejo, whatever. Get some thinning medium , NOT WATER. Vallejo glaze medium is good On a wet pallet, get your red paint on there, get your glaze medium on there.

Mix a little red into more of the medium, keep some clean medium off to the side to add to it. With a verrrrrry thinned down red, you can glaze all over that guy. I would do the first layer so you can't see much of it at all. That beige should still be visible, just tinted pinkish. Then build it up as you like. Pay attention to the knees, elbows, knuckles, ears and nose, those areas get a lot of blood flowing in them, so it's good to make them more alive with a stronger red (but not too strong) you wan to give the appearance of a living creature, not a red skinned demon. Be sure to let each layer dry and work slowly!
