A couple of weekends ago (before the visitors descended) I spent about three hours in a morning painting up an Ork Nob. I'm not sure I've done as much to his flesh as I'd like (I didn't want him too light, but he might have ended up without enough of a highlight) but here's a quick look at the model (clockwise from the top left: undercoat, flesh basecoat, completed clothing with undercoated armour, final figure).
Hopefully, having been prompted by some of the "Year in Industry" lads (University students) that I work with, I'll eventually get round to writing a "How to paint an Ork Nob in three hours" article.
[edit] Corrected the description of the photos
