have you tried removing the armor and then painting only the body first? then, after you're finished with it, you can paint the armor separately and put the figure together in the end. this way, you'll evade the chance of painting the parts you didn't want to. I still don't dig the scythe-blade, looks weird.
try washing the whole body with some bright brown, or maybe a skin tone mixed with brown or even green. that should help you draw out all the detail on the skin. as Sabres said, adding some spots here and there would be a good idea. bright dreads will also be good for an albino.
keep us posted, because now we're going somewhere.
