Now let's paint the plaster base. DON'T seal it! plaster is great precisely because it drinks the water. Anyway, i used much diluted Valejo air paints, wet on wet on wet etc
The big shadow is of course the place where the half hollow metal sheet will be, the dark traces on the clear ground are the shadow of the poor fellow.
Then I put some vallejo pigments fixer and dropped some pigments at the right places and in the end i just had to paint the guy, mostly with pigments, half diluted in acrylic paints.
Notice that most of the diorama is mat, except the helmet of the guy which is gloss white. you wouldn't believe the final effect! the eye is really attracted by that simple thing
